780A004 Obermaiselstein
position
Allgäu Alps The sequence of layers of the green sandstone is z. Sometimes incomplete, which is typical for the facies area of ​​the central helvetic region (after A. Heim, 1916). The reason for this is the uplift of the sea floor during the lower Cretaceous to Middle Cretaceous. The Schrattenkalkfelswand gives a good insight into the structure of the rock: accumulations of bivalves and corals, organic debris limestone and small reefs lie in the approx. 30 degree inclined layer sequence. 4000

Main dolomite folds on the Wiedemerkopf in the Hintersteiner Valley 780A031 Bad Hindelang
position
Allgäu Alps The Wiedemerkopf consists largely of main dolomite, which was deposited during the Upper Triassic in a lagoon (low water circulation, high salinity) with a thickness of up to 2000 m. Since the main dolomite is very rugged, it breaks up into small pieces that form large rubble fans on the mountain flanks. The apex of an almost lying fold points to the NW, the main direction of the Alpidic ceiling thrust in this region. 60000

Helvetic silica lime at the former sulfur bath of Tiefenbach 780A034 Oberstdorf
position
Allgäu Alps The building of the former Kneipp and sulfur baths in Tiefenbach is now a hostel. During the redesign of the outdoor facilities, Drusberg layers and silica limestone from the Geißberg vault were exposed. This means that one of the deepest layers of the Helveticum in the Allgäu is easily accessible. The Kieselkalk consists of relatively dark limestones with grains of quartz sand and chert lentils, which are partly formed from the abundant needles of silica sponges. The Drusberg layers - exposed south of the house entrance - consist of dark, schisty marls with limestone banks. The sulfur spring, which has been used for centuries, is said to have been down by the Mühlbach and has now dried up. 1200

Alpine red sandstone on the Iseler SSE from Oberjoch 780A035 Bad Hindelang
position
Allgäu Alps On the Iseler is one of the few occurrences of alpine red sandstone in the Bavarian Alps. This oldest sedimentary rock in the Allgäu was only dragged along in a few scraps at the base of the calcareous alpine ceiling. The Alpine red sandstone was deposited in terrestrial basins. The red color comes from iron oxide coatings on the quartz grains in a desert-like environment. In the east of the Bavarian Alps, instead, the simultaneous Werfen formation, deposited in a marine environment, is on the agenda. From the mountain station of the Iseler chairlift, following the hiking trail to the east in the direction of Wiedhag-Alpe, after 270 m there are two benches on a railing rib. To the north, this rib consists of the alpine red sandstone, which shows itself in reading stones and some rocks as light reddish to grayish white, fine-grained to quartzitic sandstone. The heavy vegetation with blueberries indicates the acidic soil. 2000

Exotic rocks at Kühberg SE in Oberstdorf 780A038 Oberstdorf
position
Allgäu Alps The discovery of exotic rocks - gneiss, mica schist, granite - in the Allgäu Alps caused great discussions in the early days of geology. One of these well-described outcrops was the Kühberg near Oberstdorf, where mica schist and granite were found in large blocks and slabs in the Wildflysch. Today it is assumed for most of these exotic giant blocks that they were carried into the depths from the shelf edge with turbid currents and embedded in the colorful conglomerates of the Junghansenschichten (Feuerstätter Flysch). If you do not take the path at the Oybelehalle that leads in serpentines to the Kühberg inn, but rather the path along the long side of the hall in a southerly direction, then 150 m after the hall, a footpath branches off to the left. Along this path you can find light mica slate pending greenish weathered in reading stones. 1600

Schrattenkalk of the Herzbergalpe WSW from Obermaiselstein 780A041 Obermaiselstein
position
Allgäu Alps On the Beslerrunde hiking trail from the Herzbergalpe east to the Schwarzenberg, there are plenty of fossils in the Schrattenkalk where the Karren forest shows a loosened, very pure limestone. Most of them are mussels or snails, the cross-sections of which emerge from the limestone due to the weathering. In the upper section of the path, oncoids - concentric deposits of lime around a germ - can be seen on the weathered areas of the limestone. At the beginning of the path down at the edge of the forest and again up in front of the hunting lodges on the Schwarzenberg, brown weathered green sandstones from the (and younger) Garschella formation above the Schrattenkalk are waiting. 160

Type locality of the Bolgen conglomerate W von Obermaiselstein 780A043 Bolsterlang
position
Allgäu Alps In 1829 the British geologists Prof. Sedgwick and Mr. Murchison traveled through the Eastern Alps, also examined the mass of crystalline rock on the Bolgen and its surroundings and came to the conclusion that volcanic matter had lifted up a solid block of gneiss and broken the overlying sedimentary rocks and were adjusted. F. v. Lupine first published the crystalline stones on the Bolgen in 1809. At that time he suspected more correctly that the crystalline rocks of the Bolgen, after the Alpine limestone had settled, had been transported here on a sloping surface by water and gravity. Cornelius (1924) named the sequence of layers as the Bolgen conglomerate. According to today's view, these are partly very large blocks that were deposited in canyons of the shelf slope and lie within the Junghansen layers of the Feuerstätter ceiling. Crystalline stone blocks can be found on the hill above the path. Crystalline stones from Bolgen are also said to have been used for the masonry of the Wannenkopfhütte. 3600

Manganese shale of the Allgäu formation in the Rappenalptal 780A044 Oberstdorf
position
Allgäu Alps In the rearmost Rappenalptal SW of Oberstdorf, the alpine path from the Speicherhütte to the Trifthütte crosses deep black clay stones at around 1,720 m. They stand out because of their dark color as well as their shiny polished surfaces and steel-blue fittings. It is the manganese shale of the Middle Allgäu Formation. The claystones are stored between cm and dm thick sandstones. In addition to manganese, which is hardly visible in any visible minerals, the manganese shales here occasionally contain tiny idiomorphic quartz crystals. Upon careful search, they reveal themselves by their flashes in the sunlight. From the last stop of the bus line in Birgsau it is a little over 3 hours and 770 meters in altitude to the geotope. It can be reached faster by mountain bike, but from the Speicherhütte only on a wide, but partly rocky path. 250

Allgäu Alps On the alpine path from the Schwarzenberghütte to the Käseralpe there are thin to thick-banked limestone and marl with claystones of the Kössen formation for a few 100 meters. The thin limestones show nice small folds. In the sequence of changes, the extensive fissures of the marl stones standing vertically on the layer surfaces and the close, angular kinking foliation of the clay stones can be observed very well. The contents of a moraine can be studied on a slope: Typical is the wide grain size range from large, rounded blocks to sand, silt and clay fractions. 1250

Jura, chalk and crystalline of the Arosa zone W of the Rotspitz 780A046 Bad Hindelang
position
Allgäu Alps The largest mass of mica slate in the Arosa zone in the Allgäu is accessible high up on the western slope of the Rotspitz in the Retterschwanger Valley - only pathless and difficult to access. The valley is closed to public motor vehicle traffic. To access the area, take the hiking trail to the Hasenegg Alps 800 m south of the Alpe Mitterhaus, but descend slightly to 1,260 m on a Jägersteig to the north. After 350 m, the trail crosses the watercourse that is continuously marked on the map and runs in a somewhat deeper run. You follow the rib to the left of the run uphill without a path and after a short time you will see a stream of rubble from the Rotspitz on the left. Further on the rib, at 1,330 m beyond the rubble flow, well-banked, greenish-gray marl limestone of the Schrambach-Fm. (within the Arosa zone). A step with a small waterfall above is accompanied by typical red radiolarites from Ruhpolding-Fm. educated. If you have carefully overcome the step (on the rib!), Then there are mica slate a little above it. Amphibolite can be found in the rubble next to it. The same way back! 1000

Spilite in the Arosa zone near the Gaisalpe 780A047 Oberstdorf
position
Allgäu Alps The Spilite of the Arosa zone near the Gaisalpe were already known to Gümbel (1861). The rocks, which are rare in the Bavarian Alps but typical for the Arosa zone, can be reached in the steep ascent in pasture terrain from the hiking trail to the Gaisalpsee (or at the same height without a path from the Richteralpe). In the teardrop-shaped wood above 1,320 m, the spilites, some with shiny metallic shear surfaces, are waiting. In the neighboring meadow area, pillows of the frozen pillow lavas that have flowed under the sea are piled up, as it were. Above the wood, the gussets between the cushions are filled with white zeolites in an outcrop in steep meadow terrain. On the border with chalk marl, Hornfels emerged from contact metamorphosis. 7500

Spilite of the Arosa zone on Rothplattenbach NE of Hindelang 780A049 Bad Hindelang
position
Allgäu Alps Gümbel was familiar with the great exposures (= outcrops) of Alpenmelaphyr in Rothplattenbach. Blocks of rock had been transported from the creek down to the vicinity of the Ostrach. These spillages in the Arosa zone have been mapped at several points in the ravine of the Rothplattenbach. They can be easily reached on a path that branches off the non-public road to the Hirschalpe at 1,300 m to the west (and leads over the Krähenwand to the Hirschalpe). After the first bend and the crossing of the stream, it is soon noticeable that instead of light limestone, there are also dark basalt gravel in the path. Spilite can now also be found in the embankment and in reading stones a long way up the rib between the two streams. Finds of zeolites are reported from the Spiliten vom Rothplattenbach. 10200

Quarries at the Oberzollbrücke NW of Sonthofen 780A051 Often swing
position
Allgäu Alps The Reiselsberg sandstone used to be a popular building block that was extracted in numerous quarries in the Allgäu. The series consists mainly of sandstones. Mudstone intermediate layers recede considerably and often only form layer joints. This is attributed to the fact that turbidity flows have largely worked up the fine-grain sediments of the previous deposit. At the Oberzollbrücke near Sonthofen there are two former quarries that are known for their beautiful sole brands. V. Rad (1972) drew a bank sequence profile with sediment structures from the quarries. Today both quarries are heavily overgrown. But sole marks can still be found on sandstone slabs lying around. The walls of steep flysch sandstone are partly overhanging due to the dismantling and sliding of blocks. The northern quarry is also quite high. Keep away from areas at risk of falling rocks! Respect private land! 32000

Ceiling boundary above the Rappenseehütte SSW from Oberstdorf 780A052 Oberstdorf
position
Allgäu Alps At the Rotgundspitze above the Rappenseehütte, the thrust path of the Lechtal Nappe on the Allgäu Nappe is visible from afar. The light main dolomite (triad) of the Lechtal ceiling lies on folded dark marl stones of the Middle Allgäu formation (Jura). In the depression between Rotgundspitze and Linkerskopf, the ceiling thrust strikes out. The Linkerskopf is built from limestone and marl stones from the Lower Allgäu formation. Towards the SW, the thrust orbit disappears under the rubble of the main dolomite and only reappears south of the Rappensee - now more than 200 m deeper. The access from the Rappenseehütte to the Heilbronner Höhenweg leads past below the geotope. It's a good 3 1/2 hours and 1,140 meters in altitude to get to the hut from Birgsau. 50000

Kargzeche W coal mining in Geratsried 780G003 Missen-Wilhams
position
Allgäu Molasse foothills The Kargzeche on Rotheidebach was operated from 1913 on a coal seam a few meters thick in the lower freshwater molasse. Two tunnels were driven, but the poor thickness and quality of the coal, water ingress and other difficulties soon led to the work being stopped again. The dismantling was started again several times, each time not of long duration. The last attempt ended in 1949, and with it a chapter in the mining history of the Allgäu. Today there are hardly any traces of earlier mining to be found on the Rotheidebach. A cut in the terrain with a water outlet suggests a collapsed tunnel. Elsewhere in the embankment of the stream, there is a wooden beam and, above it, coal-like overburden. The geotope can be reached from the hiking car park east of Trabers. 3000

Hölloch shaft in the Mahdtal WSW of Oberstdorf 780H002 Oberstdorf
position
Allgäu Alps The Hölloch is currently (2016) with 11,346 m measured length the fourth longest cave in Germany. The cave has a height difference of 452 m. The height of the cave in the karstified Schrattenkalk limestone, which is only about 100 m thick, results from its course with the inclination of the layers. The Drusberg layers, which are only slightly permeable to water, form the karst base. The entrance shaft is 76.6 m deep and can only be negotiated with rope by experienced cave explorers. The Höllochbach flows at the foot of the shaft. There are gorges, cave lakes and waterfalls through which water flows. When the snow melts and heavy rain, the entire upper Mahdtal drains into the cave and puts it under water. The water of the NW-SE cave system leaves the cave at 1,040 m at the Sägebach spring in the Schwarzwasserbachtal (Vorarlberg). From the Mahdtalhaus in Kleinwalsertal, the Höllochschacht secured with a rope railing can be reached in about 1 1/2 hours on foot. 34038

Karst landscape of the Gottesacker plateau and Hohem Ifen 780R041 Oberstdorf
position
Allgäu Alps The Gottesacker plateau north of the Hohen Ifen (2230 m) is one of the most fascinating karst landscapes in the Alpine region. On the bare or mountain pines plateau made of Schrattenkalk you can see deep crevices along intersecting faults and an abundance of cart shapes: grooved carts, gutter carts, cleft carts. At the Gottesacker-Alpe, sandstones of the overlying Brisi subformation can be found in the hollow core and in places in fossil karst pockets. The grass growth on the loamy, weathered residues of the glauconite-rich sandstones made it possible for the pasture to be farmed here in the first place, which has long since disappeared. The Gottesacker plateau can be reached from the Kleinwassertal from the middle station of the Ifenbahn, via the Mahdtal or from the Rohrmooser Tal via Windeck- and Toreckscharte. The ascent of the Gottesacker plateau requires constant attention: the hiking trail on the rock often runs next to and between deep crevices. Therefore only undertake the long tour when the weather is nice and stable, carefully follow the markings and take plenty of drinks with you! 4050000

Hirschsprung S from Obermaiselstein 780R042 Obermaiselstein
position
Allgäu Alps The Hirschsprung on the Obermaiselstein - Tiefenbach road is not a technically created road breakthrough, but is the now dry gorge of an older Breitach. The valley from Tiefenbach to Hirschsprung is likely to have been created in the Riss-Würm interglacial (126,000 - 115,000 before today). At the Hirschsprung you can see a lateral shift of about 100 m offset with harness strips and accompanying crevices. It formed the zone of weakness that erosion could attack. For centuries, until the Breitachtalstrasse was built, the transport route through the Hirschsprung was the only connection from Tiefenbach to Oberstdorf. There is a legend about the name of the Hirschsprüng about a fleeing stag who jumped over the 20 m wide gorge, but it is more likely that the first cartographer misunderstood the Ürschprüng (origin of the Riedbach below) of the locals. The Riedbach has beautiful meanders. In 2011 there was a rock fall of around 200 m³ at the Hirschsprung, which made it necessary to close the road and then rehabilitate it. 3000

Nagelfluhfelsen on the Siplingerkopf 780R044 Blaichach
position
Allgäu Molasse foothills In the area of ​​the Siplingerkopf, the layers of the Weißach Formation are almost vertical. The change from weather-resistant, coarse-grained conglomerate layers to more easily erodible fine-grained sandstone layers has resulted in the conglomerates being carved out as ribs and rock towers. The Siplinger Needles in the north ridge of the Siplingerkopf and the rocky ridges and gorges in the east flank are particularly spectacular. 360000

Helvetikum at the Scheuenwasserfall SSE von Balderschwang 780R045 Balderschwang
position
Allgäu Alps On the way from the Scheuenalpe to the Scheuen waterfall, the typical architectural style of the Helvetian ceilings with the steep northern flank of a fold forehead can be seen on the Gauchen walls in the west. Towards the south there is a flat saddle flank above the wall, not visible. Near the waterfall, the hiking trail runs under a wall of Schrattenkalk, which is set back to the south on a fault shortly before the fall step. As a result, the water of the fall falls over glauconite sandstones of the Garschella formation. In a normal position they would lie on the Schrattenkalk, here they stand - tilted - in front of the Schrattenkalk. As hard sandstones, they are recognizable by the angular tips on which the water falls and by the brown weathering colors. Seewer Kalk is mapped in the creek bed at the foot of the waterfall. The dark clay marl stones on the western side of the stream belong to the Amden formation. 5000

Land slide on Immenstädter Horn S of Immenstadt 780R046 Immenstadt im Allgäu
position
Allgäu Molasse foothills After heavy rainfall in September 2005 occurred above the access to the Steigbachtobel at 950 m above sea level. NN first cracks parallel to the slope. In March 2006, the movements accelerated dramatically. A clearly visible breakaway area was created. Falling and sliding masses moved downwards and triggered a secondary slope movement where they came to rest. The debris flow endangered the elevated tank of the water supply of Immenstadt and destroyed the water pipes from the drinking water sources in the Steigbachtal. The access to the entire Steigbachtal was interrupted. There was a risk of the Steigbach damming up with the possible consequence of a mudslide as far as the urban area of ​​Immenstadt. The dangers were largely eliminated through extensive construction work. The deforested slope is still visible from afar. 48000

Worm-age moraine near Hagspiel 780R048 Oberstaufen
position
Allgäu Molasse foothills At an altitude of 975 m, the Weißach lobe of the Bregenz-Ach glacier from the Würm period has left a perfectly formed bank moraine near Hagspiel. Shore moraines are the relics of lateral moraines after the glacier melted. They show a steep side facing the ice. After NE, the moraine wall is followed by a ridge of the Steigbach strata. There is a chapel on the moraine ridge. 137500

Large post-glacial slide E from Aach 780R049 Oberstaufen
position
Allgäu Molasse foothills To the west of Aach there are extensive landslides of molasses mixed with glacial sediments on an area of ​​1.4 km². The edge of the break is at 900 to 1000 m above sea level. NN above the long wood in Steigbach layers. The slide area is characterized by an extremely restless morphology with numerous neck valleys and drainage-free depressions. Water only flows in sections in the channels, as it repeatedly seeps into the subsoil. The landslide from the upper slope must have driven over fine-grain lake sediments in the valley area and partially incorporated them. Along the Weißach north-east of Aach, a secondary edge can be observed, where the sliding mass with the underlying sea clays has started. 2250000

Bunk layers at the Krebswasserfall WSW in Oberstaufen 780R050 Oberstaufen
position
Allgäu Molasse foothills The waterfall of the Weißach near Krebs is caused by a conglomerate bank in the bunks. The river runs more than 600 m above between banks of conglomerates before it manages to overcome the barrier at a waterfall. The step over which the water slides rather than falls coincides with the stratification. As a result, the sandstones and marl on and between the conglomerates can be clearly seen. Sand and stones carried along by the water have carved out whirlpool pots. The fine sediments that can be seen on the bank in the quiet area below the waterfall can be the sea clays that were found near Aach along the Weißach under the Worm times moraine and gravel. In the upper area they are moved by landslide processes (Geotope 780R049). 2500

Bunk layers at the Eibele waterfalls WSW in Oberstaufen 780R051 Oberstaufen
position
Allgäu Molasse foothills To the upper Eibele waterfall, cross the little bridge after the Eibelemühle to Vorarlberg and then turn directly to the right. The water of the multi-level fall tumbles over the ridge of nails in the bunks. The sandstones and marl lying between the conglomerates are exposed at the edge of the basin under the fall. The path to the lower waterfall leads past the Eibelesee down to the power station. On the way, the Nagelfluhrippe is exposed in the bunks, over which the Crab Waterfall (Geotope 780R050) falls further west. In normal operation, when almost all of the water is drained, the sliding surface of the water visible from the power plant is almost dry. The surface is the layer surface and thus shows the incidence of the layer sequence. 50000

Flysch from the Foldbachtobel E from Oberstdorf 780R052 Oberstdorf
position
Allgäu Alps In a ravine with a waterfall, the ravine overcomes the 430 meters in altitude between the hanging valley of the Seealpe and the Trettach valley. The valley floor of the Seealptal hangs so high above the Trettach valley because the glacier in the side valley did not have the ice height and therefore did not have the strength to deepen like the glacier in the main valley. When entering the ravine from Oberstdorf, alternate layers of sand-lime bricks with marls from the Tristel formation are pending. The 12 m high Fold Bach waterfall also falls over these layers. After a table on a lying rock fold in the Tristel formation (geological teaching and hiking trail Oberstdorf - Nebelhorn), the quartz sandstone-clay marl alternation of the deer ditch formation (quartzite series) begins. The path leaves the ravine and leads on a construction road to the new power plant. After a landslide, the sandstones of the Reiselsberg formation on the road had to be secured with anchors and nets. On the slope above there are aptych layers from the Arosa zone. 80000

Land slide on the Iller slope N of Altusried 780R053 Dietmannsried
position
Iller-Lech young moraine region On the steep slope of the Iller opposite Fischers, 2.7 km north of Altusried, a landslide came loose in 2012. About 30,000 m³ of mass slid downhill to the Iller. Numerous trees fell and are still on the area today. Marl stones and conglomerates of the Upper Freshwater Molasse are exposed at the trailing edge. The landslide is not yet visible in the current (Feb. 2017) digital terrain model from the laser scan flight from 2009 (Fig. 4). In contrast, an older landslide can be seen very nicely to the east of it. This, in turn, is not visible to the eye from the opposite slope due to its forest cover. Both landslides are recorded as Georisk objects. Landslides on the steep molasse slopes of the Illertal, eroded by the river at the base, are not uncommon. Alt-Kalden Castle, 1.3 km to the west on a spur between Iller and Kaldener Tobel, had to be abandoned before 1500 due to the loss of substance through landslides. Today there is only a fine line left from the former location. 14400

Rock fall on Rubihorn NW of Oberstdorf 780R054 Oberstdorf
position
Allgäu Alps Below the north flank of the Rubihorn, a block of rubble is evidence that extends from the foot of the steep face at approx. 1,400 m to the Gaisalpbach and there reaches a width of 600 m, due to its composition of old and fresh debris from old and recent falls. The boulders have detached themselves from the ridge of the steep face at 1,720 m or from the wall area itself. The rubble cone is built up from stones and blocks that can reach a size of up to 2 m³. Between approx. 1,500 m and 1,720 m, a large rock fall with a volume of around 50,000 cbm broke off in early July 1987. The fresh rock fall material now covers most of the debris cone. In the demolition area, large, loosened, fall-prone areas can still be observed on the ridge. Open crevices can be found behind the ridge. The cone of debris that existed before the last fall testifies to the unstable conditions in the entire wall area. The strong fissuring of the main dolomite is the reason for this. 231000

Rows of sinkholes on the Drehersalpe SW of Missen 780R056 Missen-Wilhams
position
Allgäu Molasse foothills The hiking trail from the Drehersalpe to the Baldaufalpe is crossed by remarkable rows of sinkholes. The sinkholes, lined up like a string of pearls, follow the stroke of the Steigbach strata. Since there are only a few scree lentils or Nagelfluh banks in the Steigbach strata of the Salmaserschuppe, the karstification of conglomerates of predominantly carbonate scree observed elsewhere cannot be the cause of the sinkhole formation here. The mechanism described by Scholz & Strohmenger must have been effective here: water paths have formed on the fissures of sandstone between the predominant marls of the layer sequence. These fissures are widened by the movement of the slope and the lime dissolution, so that they form a drainage system for the surface water. Troughs in which water seeps widen due to increased limescale dissolution, removal of fine material from the softened marl and subsidence to pseudo-sinkholes. 59500

Kare on the Wertacher Hörnle 780R057 Wertach
position
Allgäu Alps The Wertacher Hörnle is an easy and popular hiking mountain, famous for its view and for the alpine rose bloom in early summer. During the last ice age, the mountain stood out as a nunatak from the ice streams that left the Alps. A local glaciation formed the two cirques of the Kessel and the Hörnlesee. The Wertacher Hörnle is made up of tightly folded sandstones from the Reiselsberg Formation and limestone to clay marl stones from the Piesenkopf Formation. The cover of J. Bauer's Geological-Botanical Walks in the Allgäu (1983) is adorned with a photo of a fold in the flysch rock with alpine roses from the Wertacher Hörnle (Fig. 4). The crease could not be found today. 280000

position
Allgäu Molasse foothills Between Oberstaufen-Weißach and Steinebach, the deepening of the Weißach in post-glacial gravel has left behind impressively shaped terraces. During the Würme Ice Age, the Weißach tongue of the Bregenz-Ach glacier was still advancing here in the direction of today's Oberstaufen. It left a trough valley with a ground moraine on which gravel was deposited with the post-glacial deepening of the Weißach in the Nagelfluh chain near Steibis. 390000

Giant boulder The stone near Stein SE von Betzigau 780R059 Betzigau
position
Iller-Lech young moraine region The giant boulder, which is broken several times and lies in the valley floor northeast of Stein, probably gave the village its name. According to Müller (2011), the boulder made of molasse conglomerate is the largest in the Kempter Forest with around 3,300 m³ (8,580 t). There are said to be drill holes in the stone and its original size is assumed to be 11,000 t. The boulder is not signposted and can only be reached without a path. 900
