Gypsum of the Raibl Formation in the Schwarzenbachtal SW of Lenggries 173A027 Lenggrie's
position
Isar-Loisach mountain region The best outcrop in the gypsum of the Raibl formation in the Bavarian Alps is in the Schwarzenbachtal near Lenggries. At the object point on the other side of the stream there are large blocks of crinkled gypsum rock (gypsum-marlstone interchangeable bedding), which presumably fell from an earlier excavation wall. 100 m further upstream, below the forest road, the Schwarzenbach and fallen trees have exposed cliffs of gypsum rock. Be careful here: Danger of falling rocks and falling trees on unstable ground! Gümbel describes the gypsum breaks in the Schwarzenbache as very extensive and productive, but only give dung gyps. ... The shipment takes place on the Isar. Gypsum was extracted here at the beginning of the 18th century. The first photo from the 19th century shows numerous mining plots. It is 4.6 km from Langeneck south of Lenggries at the valley exit of the Schwarzenbach to the geotope. 2400

Ried lime kiln 173G003 Kochel am See
position
Isar-Loisach young moraine region The lime kiln has been owned by the Streidl family, Ried, since secularization. The limestone required for burning is collected by hand as limestone gravel in the Loisach Valley. For lime burning, the stones are piled up in the kiln and burned with wood burning at over 1000 degrees. After quenching with water and storage, sump lime is produced. The last time it was burned in the lime kiln was 2010. The lime found sale for the traditional whitening of churches, monasteries and castles. But since other colors are increasingly being used here, it is questionable whether the stove can be stoked up again. Private! Do not enter without the consent of the owner! 600

Sylvenstein on case 173R024 Lenggrie's
position
Isar-Loisach mountain region The Sylvenstein is the rock face on the east side of the Isar valley north-east of Fall. The first photo (Fig. 4) shows the landscape in the 19th century. In the 1950s, the Sylvenstein reservoir was dammed here by a dam. Extensive geological investigations preceded the construction of the dam. Drilling at the narrow point resulted in a valley filling of up to 93 m thickness under the Isar bed. The almost vertical east wall with scouring and overhanging parts and a narrowly cut gorge at the deepest point was remarkable (Fig. 3). Pleistocene sea chalk moves in the valley sediments over the gorge. The gorge itself cannot have been created by ice or meltwater at the bottom of the glacier, but must have been created by flowing water in an earlier interglacial. An uncovered tunnel for cyclists and pedestrians leads through the rock made of main dolomite. 100000

Quarzbichl sand pit W 173A020 Eurasburg <
position
Isar-Loisach young moraine region In a sand pit west of Quarzbichl, the Upper Nonnenwald sand is exposed with layers of coal and fine gravel. The light-colored quartz sandstone, weathered to form sand close to the surface, was formerly known as Upper Glass Sand. It comes to light here in the core of the northernmost hollow of the fold molasse (Nonnenwald hollow). The information lies in the Dachsbichl and Stuchlik wrote in 1906 that the glass sands could be found on the basis of the fox and badger burrows almost exclusively in these uniformly fine-grained sands and that lucky searches for Reineke's looted caves could even help solve difficult geological problems. The sand pits near Quarzbichl - the old pits were 300 m ESE at today's edge of the forest - are said to have supplied all southern Bavarian glassworks - in the vicinity: Nantesbuch, Benediktbeuern and Grafenaschau - with quartz sand. In the first Bavarian photograph from 1810 (Fig. 4), next to the sand pits, Mr. v. Utzschneider - the owner of the Benediktbeurer glassworks. 3000

Alpine red sandstone in the Sonnersbachtal E of Lenggries 173A028 Gaissach
position
Mangfall Mountains Alpine red sandstone is rarely open in the Bavarian Alpine region. In the furthest corner of the Sonnersbachtal, on an embankment and in a ditch next to it, there are splintered-hard red sandstones, mica-bearing, banked, with mudstone intermediate layers. Ripple marks and traces can be seen on the layer surfaces. Brown, cellular dolomites and a few meters of dolomitic limestones of the Reichenhall Formation adjoin the Alpine Buntsandstein, followed by the limestones of the Virgloria Formation (Lower Alpine Muschelkalk). Here in the Sonnersbachtal are the only places in Bavaria where the Reichenhall Formation in the stratigraphic network between Alpine Buntsandstein and Alpine Muschelkalk can be clearly identified. The second outcrop is about 260 m ENE from here and can be reached by walking back 200 m on the path and taking the forest path uphill to the east. After the curve above the meadow, red sandstones appear in the gravel. Here up a wooded rubble fan and in the adjoining gully there is alpine red sandstone and reading stones from cell dolom with the Reichenhall formation. 400

Till, basin silt and gravel on the Rißbach S from Vorderriß 173A030 Lenggrie's
position
Isar-Loisach mountain region At the edge of the valley on both sides of the Rissbach, north of the Oswaldhütte Till, there are strewn debris, silty reservoir sediments and mighty gravel, gravel and sand from the late worm to post-glacial age. Here in the lower Rißbachtal the localis of the Rißbach glacier met the distant ice of the Isar glacier. The silts were deposited when glacier ice in the Isar valley prevented the Rissbachtal from flowing out and a lake was dammed. Delta gravel poured into the lake intermesh with the fine sediments. In the alternation of ice advance and retreat, several lakes can have formed. The Rissbach later sank into the mighty gravel that was deposited with the ice retreat, but it also created new terraces. 60000

Tufa on the Riedbach W of Sachsenhausen 173A033 Egling
position
Isar-Loisach young moraine region The water of the Riedbach west of Sachsenhausen is highly calciferous. In addition to mossy tuff terraces, the stream has an almost petrified stream bed in places. Caddis fly larvae are found in abundance. Worm-like tubes at the bottom of the brook are living tubes of mosquito larvae. They are encrusted by lime-separating green algae and can build up tufa layers. The brook is deepened in loose limestone tuffs, several meters thick, which also contain black organic layers. The profile described in detail in the explanations of the geological map in these deposits of more than 8 m thickness should be the profile at the object point (impact slope). The RH value given in the explanations is then incorrect. In places on the slope of the valley there are also hard limestone sinter with hollow forms of reeds and stalactite-like shapes. The calcareous waters come from Pleistocene gravel over moraine or on molasse subsoil. 1500

Kalktuffe W from Achmühle 173A034 Münsing
position
Isar-Loisach young moraine region West of Achmühle, on the slope of the Loisach valley, lies a bumpy slide area that is criss-crossed by numerous lime-separating spring streams. In the streams, limestone tuffs are formed as encrustations of mosses, branches and pebbles and as tufted terraces. Stream sections show that the subsoil also consists of loose limestone tuff or washed up limestone tuff sand. The groundwater is likely to originate from - mapped a little further south - crack-age meltwater gravel over conglomerates of the Upper Freshwater Molasse (OSM) and emerge on damming marls of the OSM. The overburden of the Würmzeit moraine is very wet and has moved down the slope as a result. The restless terrain is likely to be partly due to the excavation of tufa. 120000

Isar-Loisach young moraine region The Schindergraben is mostly dry valley in its upper reaches. Mindelzeitliche Nagelflühen stand on the slopes and form steps in the stream bed. Where the ditch is water-bearing again, the damming marls of the Upper Freshwater Molasse come to light. Incidentally, immediately above this, the Pleistocene gravel has not hardened to Nagelfuh. On both sides of the exit of the Schindergraben into the Isar valley at the Naturfreundehaus there is a wide slide area with neck valleys and clods of Nagelfluh. The nail feet have slipped on the superficially soaked, soft molasse marls. A gallery of spring outlets runs along the foot of the slide. 150,000

Type locality of the Tratenbach layers ENE from Lenggries 173A039 Lenggrie's
position
Mangfall Mountains On the Tratenbach east of Lenggries is the type locality of the Tratenbach layers. The Tratenbach layers are a turbiditic sediment sequence consisting of sandstones, marls and conglomerates with a sandy matrix. Most of the pebbles are of volcanic origin (porphyry). Between 960 and 980 m, the Lower Tratenbach strata with conglomerates are well exposed on the Tratenbach. The Tratenbach strata connect to the Losenstein Formation and have an age from Obercenoman to at least the Paleocene. The layers were deposited as synorogenic sediments during the alpine mountain formation on the later limestone alpine marginal scales and the Allgäu cover. At the same time as the Tratenbach strata, the fire spot formation was deposited in front of the approaching Lechtald ceiling forehead to the south. While the Branderfleck formation contains calcareous alpine components of the Lechtal cover, the Tratenbach layers contain volcanic rocks as exotic pebbles. The delivery area of ​​the Tratenbach strata is seen in a ridge to the north - also interpreted as an accretion wedge (Fig. 4 from Willscher 2004). 1500

See chalk on Staffelgraben W from Sylvensteinsee 173A040 Jachenau

Isar-Loisach mountain region Sea chalk used to be mined at the lower Staffelgraben. The name of the old chalk quarry indicates this. Traces of degradation have long since slipped over. A profile exposed over 50 m in height by landslides and rinsing shows impressively gravel and sand over basin silts (sea chalk). The basin silt is placed in the early Würm and is likely to have been deposited when the gravel of the advancing ice in the Isar valley blocked the side valley and a reservoir formed. 110 m further on, the basin silts with strewn scree layers are opened up again on a collision slope. 3200

Hell pit on the SE side of the Benediktenwand 173R025 Jachenau
position
Isar-Loisach mountain region On the southeast side of the Benediktenwand, surrounded on three sides by Wetterstein limestone, there is a drainless depression of remarkable depth, the Höllgrube. Compared to its southern boundary, it has a depth of 57 m. At the eastern edge of the Höllgrube, the Partnach formation is in the core of the Höllgrube saddle. How the hell pit came about can only be guessed at. On the eastern edge of the Höllgrube and further east around the Scharnitzalm there are many small sinkholes in the Partnach Formation and in the Alpine Muschelkalk, which, however, cannot explain such a deep hollow shape. It is believed that an old karst hollow was remodeled here by local glaciers. The hell pit is therefore called the cardoline. The basin floor has a rare snow-floor vegetation. A meltwater lake forms briefly in May / June. The result of a tracer input into the lake suggests a complicated drainage system in karst / fissured aquifers to the SW sources of the Bichler Alm. 60000

Impact slope of the Isar W from Bairawies 173R049 Dietramszell
position
Isar-Loisach young moraine region On the Isar, west of Bairawies, it can be observed how an impact slope shifts into meadow terrain and how agricultural areas are lost. In this area, the Isar is to receive (back) its natural flow dynamics. Therefore, old barriers to protect the bank had been removed from the river a long time ago. As a result - especially during floods - the worm-age basin silts on the bank are eroded and the overlying meltwater gravel roll or fall into the river. These compensatory movements up to a meanwhile stable angle of slope continue upwards over the entire 11 m high slope until finally the grass sods above also tear off. They are scattered over the entire slope in their downward movement. To let the river dynamics of the Isar run free here is desired for nature conservation reasons. The state has therefore acquired a strip of meadow bordering the river that can no longer - or soon no longer - be cultivated. Attention! Keep a sufficient distance to the unstable slope edge! 2400

Humpback meadows of the Königsdorfer Alm S from Geretsried 173R050 Königsdorf
position
Isar-Loisach young moraine region Humpback meadows represent a geomorphological peculiarity of the Alpine region. The processes that led to their creation can, however, differ depending on the location and the substrate. At the Königsdorfer Alm, high-worm-age carbonate meltwater gravel is the substrate on which humpback meadows have developed. Gravel shows up where the bumps are cut. A differentiated initial relief can arise from the fact that where water drips off trees or snow remains for a long time, the carbonate solution attacks more intensely. The resulting relief is exposed by clearing or a new relief is created. The concentration of the runoff in the troughs then contributes to further carbonate dissolution and hump formation. The humpback meadows at the Königsdorfer Alm and around meadows represent the northernmost humpback meadows in the Upper Bavarian Alpine foothills. 240000

Ice crumbling landscape of Kirchsee and Kirchseefilzen 173R053 Bad Toelz
position
Isar-Loisach young moraine region Kirchsee and Kirchseefilzen are the relics of the Zungenbeckensee of the Tölzer Lobus of the Isar-Loisach Glacier. There are indications that a large mass of dead ice slowly melted here beforehand. Gravel and gravel were poured against this ice from W to SW. Piles of gravel against ice are known as kames. At the point of the object, the former edge of the dead ice emerges as a wall. The irregular relief to the west of it is caused by the overflow of smaller dead ice masses. When they melted, dead ice holes remained. Where the large dead ice melted in the east, a lake formed, which was first filled in with gravel and finally silted up with silt and clay deposits up to today's Kirchsee. Moors developed in his environment. 3600000
