Gravel pits at Johannis-Keller E of Obergünzburg		777A001	Obergünzburg position	Iller-Lech region	The gravel and conglomerates exposed to the north of the road in a former quarry presumably represent at least Ice Age advancing gravel overlaid by a Mindel moraine. Lempe (2012) thinks it is also possible that the ballast can be divided into a lying Günz- or Danube-Age meltwater ballast further away from the ice edge and at least-age moraines and ballast in the hanging wall and that above it lies a crack-age moraine. Access to the former mining north of the road is blocked. The exposed wall can, however, be viewed quite well from outside. Gravel mining is currently in operation in the south.	17500 250 × 70	Type: Layer sequence Type: moraine, conglomerate, gravel	Gravel pit / sand pit	precious	no protected area
Former Gravel pit NE by Moosmühle		777A002	Untrasried position	Iller-Lech region	The stratigraphic assignment of the partially conglomerated fluvioglacial gravel is unclear, presumably it is minelglacial gravel.	4250 85 × 50	Type: Rock Type: Conglomerate	Gravel pit / sand pit	significant	no protected area
Outcrop in the ravine NW of Hinterschmalholz		777A003	Untrasried position	Iller-Lech region	The outcrop in a slippery slope represents an important Quaternary profile.

Quarries on Hornburg E from Schwangau		777A020	Schwangau position	Ammer Mountains	From 1945 to 1960 Hierlatzkalk (Adneter facies) was mined here as red marble. Hierlatzkalk is related to a disturbance and was mined as red tuber lime and used as natural stone or for craft marble products.	36000 200 × 180	Type: Rock, Quarry / Pit Type: Limestone	Quarry	significant	Nature reserve
Type locality Reiselsberger Sandstein SE from Buching		777A021	Halbch position	Ammer Mountains	The outcrops at the entrance of the Tiefenbach valley are close to the type locality a little further to the east, where no more outcrops are available today. Beyond the bridge, the clayier Piesenkopf layers follow over the sandstone. The Reiselsberg sandstone, with its thick banked (0.5 - 3 m) fine to coarse sandstones, forms the most typical series of the flysch zone, the sandstones are always limy and rich in mica.	7500 300 × 25	Type: Type locality, rock type, sedimentary structures Type: sandstone, marlstone	Impact slope / river bed / stream profile	precious	Nature reserve, FFH area, bird sanctuary
Wertachkerbtal N from Nesselwang	more pictures	777A022	Nesselwang position	Iller-Lech young moraine region	In the Kerbtal of the Wertach under the A7, sandstones and conglomerates of the fold molasses are exposed. The Wertach Valley with its imposing A7 bridge cuts the north wing of the Murnauer Mulde with steep sandstone and conglomerate banks of the Steigbach layers.

Reiselsberger sandstone at Schrofeneck SE from Zell		777A023	Feet position	Iller-Lech young moraine region	Here is an outcrop of Reiselsberg sandstone located very far to the north. On the wooded Schrofeneck there is a large outcrop of massive to banked sandstone, heavily fissured and collapsed and with structures that suggest earlier mining.	60000 400 × 150	Type: rock type, sediment structures, quarry / pit type: sandstone	Rock slope / cliff	precious	Landscape protection area
Quarry at Hochholz S in Nesselwang		777A024	Nesselwang position	Allgäu Molasse foothills	In the quarry on Hochholz, the steep sequence of layers from various green sandstones from the Garschella formation to Seewer Kalk is exemplary. There are processing horizons with phosphorite tubers.	600 30 × 20	Type: Sequence of layers, sediment structures Type: Limestone, sandstone	Quarry	precious	no protected area
Quarries on the Kienberg-Südhang SW of Schwangau		777A025	Schwangau position	Ammer Mountains	The quarry Schwansee West is located directly on the Königsstrasse north of the Schwansee. A light variety of Partnach limestone was extracted here. The stone was traded under the name Alterschrofener Marmor or Füssener Steinbruchkalk and is z. B. installed in Neuschwanstein Castle and in the Church of St. Mang in Füssen. The quarry is relatively easily accessible, but overgrown. In the eastern part there are residual outcrops, in the western part a large dump. Schnetzer (1941) reports that the limestones were covered by Pleistocene sediments with shale coal. It is not known whether this information can still be found today.	37800 420 × 90	Type: Rock, Quarry / Pit Type: Limestone, Clay Marlstone	Quarry	significant	Landscape protection area, FFH area, bird sanctuary
Quarry at Ettwieser Weiher S of Marktoberdorf		777A026	Marktoberdorf position	Iller-Lech young moraine region	In the overgrown quarry, a sequence of layers is exposed, predominantly with banked middle sandstones from the top of the Upper Sea Molasse. Current and wave ripples can be found on layer surfaces. Schillbänke are switched on and there are layers of coal tinsel. The quarry is a stop on the Terra Nostra (for adults) and Klobunzele-Weg (for children) hiking trails.	2925 65 × 45	Type: Type of rock, type of layer sequence : Sandstone	Quarry	significant	no protected area
Seewerkalk on the ruins of Hohenfreyberg W von Eisenberg		777A027	Eisenberg position	Iller-Lech young moraine region	The Hohenfreyberg castle ruins are on the Helvetic Sea limestone, while the Eisenberg ruins are on Schrattenkalk. Pending sea lime can be found in several places on the castle grounds.	16500 150 × 110	Type: Layer sequence, type of rock : Limestone	Slope crack / rock wall	precious	Landscape protection area
Tannheim Formation W from the Fallmühle near Pfronten		777A028	Pfronten position	Allgäu Alps	At the Steinacher Achen west of the Fallmühle, one of the few occurrences of the Tannheim Formation in Bavaria is exposed. The outcrop in a sliding slope can be viewed from the hiking trail south of the Achen across the stream. The leafy black marl and dark gray limestone marl (chalk) are covered with Wetterstein limestone (Triassic). The landslides with the movements of blocks of Wetterstein limestone are known from ancient times, but have continued until very recently, as the areas without vegetation in the aerial photo (Fig. 4, © Bayer. Vermessungsverwaltung) show.	12800 160 × 80	Type: Sequence of layers, landslide Type: Clay marl, limestone marl	Impact slope / river bed / stream profile	precious	no protected area
Wertachprallhang E from Görisried		777A029	Forest position	Iller-Lech young moraine region	On the Wertachprallhang E of Görisried, fine sandstones of the Upper Sea Molasse are located within the fold molasses. The deposit area lay between the gravel compartments of Hochgrat-Adelegg in the west and Auerberg-Nesselburg in the east, so the sediments are fine-grained. The stratification is characterized by slightly harder layers in the rock. The dip is shallow towards NE. The impact slope is difficult to access without a path. It is easier to look over the Wertach from the west bank.	4500 100 × 45	Type: Type of rock, sequence of layers, impact slope Type: Sandstone	Impact slope / river bed / stream profile	significant	Landscape protection area, FFH area, bird sanctuary
Upper sea molasse at Leuterschach train station		777A030	Marktoberdorf position	Iller-Lech young moraine region	On an embankment opposite the Leuterschach train station and on an old quarry wall behind the neighboring inn, there is an alternating layer of medium-sized sandstones and marlstones from the Upper Sea Molasse. The banked sandstones show inclined stratification, current ripples and digging tracks. Respect private land, ask for permission to enter!	1600 160 × 10	Type: rock type, layer sequence type: sandstone, marlstone	Slope crack / rock wall	significant	no protected area
Lower freshwater molasse on the Wertach W von Wald		777A031	Forest position	Iller-Lech young moraine region	On the circular hiking trail along the Wertach between Wald and Bergers, sandstones and marl stones of the Lower Freshwater Molasse are exposed along the way and in the steep slopes on the Wertach bank.	16000 800 × 20	Type: rock type, layer sequence type: sandstone, marlstone	Slope crack / rock wall	precious	Landscape protection area, FFH area, bird sanctuary
Tufa-lime near the Gennachsäge NE of Marktoberdorf		777A032	Biessenhofen position	Iller-Lech young moraine region	To the southwest of the Gennachsäge, diffuse spring water emerges on a slope, which separates tufa. The water in ice-age gravel escapes from damming freshwater molasses. The open area above the object point shows a rare plant community as a hill spring moor and is a biotope. Therefore do not step onto the area, but look from the edge.	5000 100 × 50	Type: Rock type, hill spring moor Type: Tufa limestone	no information	significant	no protected area
Outcrop on the Lengenwang quarries		777A033	Lengenwang position	Iller-Lech young moraine region	On the Molasse Ridge W von Lengenwang, which has been smoothed by the glacier, there are several small quarries in the corridor on the quarries, in which stones were removed for building houses. In the break at the geotope point, flat to thin-banked middle sandstones of the lower freshwater molasse with clearly visible sloping leaves are exposed.	1000 50 × 20	Type: Rock type, Sedimentary structures Type: Sandstone	Quarry	significant	no protected area
Raibl formation in the Beinlandl on the SSE high plateau of halchch		777A034	Halbch position	Ammer Mountains	On the way from the Kenzenhütte (1,294 m) to the Weitalpjoch (1,778 m) in front of the Hochplatte, the Raibl formation opens up on the Beinlandl. The outcrop along the way shows the whole range of rocks of the Raibl Formation: brown-yellow to rust-red weathered sandstones, black, sandy clay slate, yellowish weathered limestone, dolomites and Rauhwacken. Immediately after leaving the Beinlandl, a coal seam comes to light on a small pass at 1,700 m underfoot. The sequence of layers on the Beinlandl and Schössel was already known to Gümbel (1861) and he described it very precisely.	2000 200 × 10	Type: Type of rock, type of layer : sandstone, claystone, lignite	Rock slope / cliff	significant	Nature reserve, FFH area, bird sanctuary
Gypsum block in the Pöllat SE of Hohenschwangau		777A035	Schwangau position	Ammer Mountains	In the Pöllat in the youth valley lies a block of banded plaster of paris. Heavy precipitation led to a landslide on the southern slope of the Youth Valley on May 23, 1999, which buried the river bed of the Pöllat. The Whitsun flood in 1999, triggered by the same rainfall, cleared the bed of the stream to such an extent that there was no damming, but only a shift in the course of the stream. In the process, the plaster of paris should also have been flushed out of the sliding masses. Since then, erosion has been working on the block, which will disappear in the next few decades or perhaps with the next flood. There is no plaster of paris to be found on the slide above or on the edge of the slide. Perhaps the lime-rich water of the Pöllat - unlike the rainwater - will prevent the gypsum from becoming more detached. Gypsum from the Raibl Formation was not far away in a quarry and tunnel that had long been buried.	4 2 × 2	Type: Rock type, Landslide type: Gypsum	Impact slope / river bed / stream profile	significant	Nature reserve, FFH area, bird sanctuary
Outcrop in the Upper Marine Molasse WSW of Stötten		777A036	Stötten am Auerberg position	Iller-Lech young moraine region	The outcrop shows sandstones, sandy marl stones and conglomerates on the western edge of the Auerberg fill fan in the Upper Sea Molasse. Scholz & Frieling (2006) describe and sketch the outcrop in detail and particularly address synsedimentary folds in the sandstones. A sandstone bank with remarkable sedimentary structures hangs high up in the outcrop. Caution, risk of falling rocks! Keep away from the overhanging wall parts!	750 50 × 15	Type: Layer sequence, sediment structures, animal fossils Type: Conglomerate, sand-lime stone, sand marlstone	Slope crack / rock wall	precious	no protected area
Pathway in the Ammergau formation ESE from Schwangau		777A037	Schwangau position	Ammer Mountains	On the recently laid-out road - closed to public traffic - from the Drehhütte to the Rohrkopfhütte, the flat to thin-banked limestones of the Ammergau Formation are excellently exposed. Pebbly deposits (chert) are striking. In the curve, a small whetstone quarry - now located above a manhole cover - has been cut by the road construction. The thin layers of whetstone consist of fine limestone with angular or slightly rounded chert grains and pebbly radiolarians. The Ammergau Formation of the Upper Jurassic goes south into the Schrambach Formation of the Lower Cretaceous. A differentiation in the terrain is not possible here.	1500 300 × 5	Type: layer sequence, rock type, quarry / pit type: limestone, chert	Slope crack / rock wall	precious	Nature reserve, FFH area, bird sanctuary
Type locality of the Branderfleck Formation SE from Schwangau		777A038	Schwangau position	Ammer Mountains	The type locality and type profile of the Branderfleck formation were defined by Gaupp (1980) here on the Branderfleck saddle. A turbiditic sequence of red clays and ocher marls lies over block breccias. There are sometimes beautiful current marks on the underside of the marl banks. Based on the microfauna, Weidich (1984) found that the higher Cenoman and Turon are missing here in the south wing of a hollow. They have been eroded and are contained in the Olisthostromes of the Mulden north wing further west, where the type profile can be completed. The geotope on the Branderfleck-Sattel can be reached on the hiking trail from Tegelberg towards Ahornsattel. Surefootedness is required. Along the path below the Branderschrofen, the basal block breccia of the hollow flanks and the hanging clays and marls of the hollow core in between are crossed. The fire spot formation lies here on the main dolomite.	5000 250 × 20	Type: Type locality Type: Breccia, claystone, marlstone	Rock slope / cliff	especially valuable	Nature reserve, FFH area, bird sanctuary
Outcrop at Hutlersberg S from Füssen		777A039	Feet position	Ammer Mountains	On the south side of the Hutlersberg there is a former quarry in limestone of the Partnach formation. The quarry is the geological resting place and playground on the GEO GrenzGÄNGER hiking trail. A climbing garden is set up, humming stone, lithophone and turning stone egg allow stones to be perceived with the senses. The sequence of shifts is steep. The gray, medium to thick banked limestones show a wavy layer surface with clay flaps. Harness surfaces show movements of rocks. A path on the north side of the quarry leads to an outcrop of clay marl stones from the Partnach formation. Above it lies a presumably moraine with debris over a thin soil horizon, whereby it is difficult to decide here whether the material was not relocated by solifluction or in the course of the mining equipment.	2400 60 × 40	Type: Rock, Quarry / Pit Type: Limestone	Quarry	precious	Landscape protection area, FFH area, bird sanctuary
Former Quarries in the Forggensee ENE von Dietringen		777A040	Schwangau position	Iller-Lech young moraine region	The quarries in the Deutenhausen layers near Dietringen were described by Gümbel and disappeared in the Forggensee after it was dammed. Around the month of March, when the Forggensee is largely drained and not yet refilled, sand-lime stone banks appear near the shore. The marl stones in between form brown stripes between the almost vertically and overturned sandstone slabs. On the undersides of the sandstone banks, the most diverse sediment marks appear like flysch and thus point to the transition from the flysch to this lowest layer sequence of the molasses. A smaller outcrop is on the western shore of the lake near Dietringen. The more impressive outcrops on the east side can be reached via the barrage at the Roßhaupten power plant or via the town of See. The water level of the Forggensee can be called up from the flood news service Bavaria (Roßhaupten Seepegel). In 2018, the Forggensee will remain drained into the summer due to repairs to the dam. Then the Forggensee reef disappears again.	28800 240 × 120	Type: rock type, quarry / pit, layer sequence type: sand-lime brick, marlstone, conglomerate	embankment	precious	Landscape protection area
Raibl formation in the creek bed of Pöllat SE von Hohenschwangau		777A041	Schwangau position	Ammer Mountains	The geotope lies in the bed of the Pöllat stream below the Hohen Straussberg. It can be reached from Hohenschwangau by bike or on foot, to Bleckenau also by bus, and then on towards Alpe Jägerhütte. Around where a hiking trail branches off to the right (to the south) to the Altenberghütte, in the meadow below the road, a trail leads east down to Pöllat. In the stream bed of the Pöllat there are sandstones of the Raibl formation with rusty iron deposits and even a seam of hard, thin-plate shale coal can be found. The uppermost Wetterstein limestone, which is described in detail in the explanations of the geological map - contains dark, elongated, lenticular sandy deposits as a special feature. It will be an early sandy bed that preceded the later Raibl Formation. If the water level is high or there is rain above the creek bed do not walk!	2100 210 × 10	Type: Type of rock, type of layers : sandstone, limestone, lignite	Impact slope / river bed / stream profile	precious	Nature reserve, FFH area, bird sanctuary
Historical mining on lignite near Irsee		777G001	Irsee position	Iller-Lech region	In the Riedgraben north of Irsee, lignite from the Upper Freshwater Molasse was mined in several periods from the middle of the 19th to the middle of the 20th century. A number of tunnels were in operation, at times there was also a branch line from Leinau to the mine. In a piece of forest 700 m northeast of Oggenried, an elongated spoil dump can still be seen. Its western end merges into a wet hollow with a stream. From here the tunnels apparently extended north and south. Pieces of coal can be found in the stream.	10000 200 × 50	Type: tunnel, dump type: lignite	Ping	significant	no protected area
Former Quarry in the Benkener Marmor SW of Oberkirch		777G002	Feet position	Allgäu Alps	The Weissensee rubble marble or Benken marble was extracted as a decorative stone between Weissensee and Benken - perhaps since Roman times. Geologically, it is a red cemented carbonate breccia with calcareous alpine components in the Lower Branderfleck Formation. Schmitz (1842) says: The master stonemason Müller in Füssen processes the limestone and dolomite breccia on the northern slopes of the Weissensee and Benkenbergs and lying around in numerous blocks on the slope and foot of the mountain as beautiful and durable rubble marble. Most likely it was mainly blocks that were processed, because quarries are not found in old maps and in nature there are only few clear traces. At the point of the object there are stones with traces of extraction, which, however, suggest a more recent experimental dismantling. Whether the meadow below was once excavated with a dump can only be puzzled, as well as whether rock was extracted from the small pits that step up the slope 50 m further south. On the south bank of the Weissensee a table and sanded stone reminds of the marble extraction.	180 15 × 12	Type: Quarry / Pit Type: Breccia	Quarry	significant	Landscape protection area
Historical peat cutting on the moor circular route W from Görisried		777G003	Görisried position	Iller-Lech young moraine region	A peat dig with soil exposure, hut, equipment and drying peat sod is simulated on the W moor path in Görisried. A photo shows historical peat extraction. In the digital terrain model - especially when superimposed on the land map - (Fig. 4), earlier peat extraction can be recognized quite easily by the terrain levels that penetrate the bog to different depths with the plots. The ditches for the peatland drainage are also clearly visible.	50 10 × 5	Type: peat cut Type: peat	Schurf	significant	FFH area
Iron ore mines of the Beinlandl on the SSE high plateau of Halchch		777G004	Halbch position	Ammer Mountains	In the Beinlandl there are traces of old mining attempts on iron in the form of dilapidated scraps and heaps. The iron ore was present as ferrodolomite and pyrite in the Wetterstein limestone or weathered as brown iron. The outcrop can be classified in a train of similar occurrences of originally sedimentary and later relocated iron or zinc ores in the uppermost Wetterstein limestone, which extends through the entire Bavarian Alpine arc. Sludgy brown iron in the Wetterstein limestone and iron-containing Wetterstein limestone, weathered from dark brown to rusty red, can still be found today. Iron ore is said to have been mined in the area of the Hochplatte as early as 1600, and most recently on the Beinlandl around the time of the First World War.	600 60 × 10	Type: Schurf Type: iron / manganese ore, limestone	Schurf	precious	Nature reserve, FFH area, bird sanctuary
Iron ore mines on the Altenbergalpe SE of Schwangau		777G006	Schwangau position	Ammer Mountains	Depressions in the terrain on the Altenbergalpe, together with evidence of pyrite and limonite in the upcoming Wetterstein limestone, suggest that ore was being mined. The ore flow of the uppermost Wetterstein limestone on the border with the Raibl formation is known. Taupitz (1954) sketched a profile with pyritized breccias from the Altenbergbach. The karst formation can create similar terrain forms as here and limonitic ores are often enriched in karst hollow forms from which they were extracted by the early ore graves. Most of the hollows and holes in the Altenbergalpe are, according to Schöner et al. (2003) nothing more than naturally formed sinkholes, since heaps and walls made of excavated material are missing, but a hand-drilled borehole could also be proven here as evidence of ore mining. In today's digital terrain model from laser scan data, sinkholes also look much more regular than the terrain here. The area is a ground monument (monument no. D-7-8430-0032).	22500 150 × 150	Type: Schurf, Dolinenfeld Type: Limestone, iron ore	Schurf	significant	Nature reserve, FFH area, bird sanctuary
Iron ore mining at Schlagstein SE in Schwangau		777G007	Schwangau position	Ammer Mountains	About 150 m to the west of the summit cross of the Schlagstein, there are scattered small hollows in the forest, which can be recognized as excavation pits by ejecta walls. Here, iron ore was searched for or mined in the uppermost Wetterstein limestone near the border with the Raibl formation. There are occasional traces of brown iron in limestone chunks. Be careful - there are also karst holes from which limonitic iron ores may have been cleared. However, there are no signs of degradation that could prove this. The area is a mining ground monument (monument no. D-7-8430-0030).	5000 100 × 50	Type: Schurf Type: Limestone, iron ore	Schurf	significant	Nature reserve, FFH area, bird sanctuary

The sinkhole field at the geotop point is the station on the Lengenwang Kleeblattweg. Water is life. The formation of the sinkholes is attributed to the washing out of sand from loosening zones in the lime-rich sandstone of the Lower Freshwater Molasse near the Lobach receiving water. Steep-walled funnels then form in the glacial till. The southern of the three sinkholes has a water outlet with a mouth (ponor) a few meters further. Unfortunately it will be filled.	7500 125 × 60	Type: Dolinenfeld Type: Marlstone	Sinkhole / sinkhole	significant	no protected area

The carts were probably uncovered when the Maximiliansweg was laid out here as a bridle path a long time ago. Such carts develop particularly well under ground cover and entire cart fields can be presumed to be under ground cover in the area. The carts lie in the karst-capable Wetterstein limestone, which shines like a marble here.	28 7 × 4	Type: Carts / Fields Type: Limestone	Slope crack / rock wall	precious	Nature reserve, FFH area, bird sanctuary
Kar of the Schwangau boiler E from Hohenschwangau		777R031	Schwangau position	Ammer Mountains	The Schwangau basin below Gabelschrofen and Niederstraußberg is the slightly deepened Karwanne of a former local glacier. During the last Ice Age, the surrounding peaks of the Ammer Mountains protruded from the Arctic Ocean, but were - especially on the north side - a breeding ground for local glaciers that flowed into the valleys. The distant ice of the Lech glacier from the central Alps could not penetrate into this valley, the passes were too high. In the Schwangau Kessel and on the Gabelschrofensattel, Partnachformation emerges in the core of a saddle made of Wetterstein limestone. The Partnach formation consists of dark gray clay marls that can be easily removed from the ice with two powerful limestone layers. The clay marls are visible from the hiking trail in the basin and are entered on the last meters up to the Gabelschrofensattel. The cirque of the Schwangau basin is clearly visible in the digital terrain model with an overlaid aerial photo (Fig. 4). (The flow structures in the Wetterstein limestone walls of Krähe and Niederstraussberg, however, are artifacts: the few pixel points from the vertical aerial photo are distributed as lines across the wall in an oblique view.)	200000 500 × 400	Type: Kar Type: Limestone, Clay Marlstone	other information	precious	Nature reserve, FFH area, bird sanctuary
