Former serpentinite quarry W from Guglöd		272A004	Sankt Oswald-Riedlhütte position	Rear Bavarian Forest	In this small quarry, the serpentinite known as black gravel was formerly mined into road and railway gravel. The occurrence of this ultra-basic rock (very rare in the Bavarian Forest) within the gneiss is probably linked to scaling from greater depths in the area of shear zones. The former gravel quarry now serves as a geological exhibit in the national park. The serpentinite scale continues on the opposite side of the street.	140 20 × 7	Type: Rock Type: Serpentinite	Quarry	significant	National park, landscape protection area, FFH area
Former sand pit in the Reschwassertal northwest of Mauth		272A006	Schönbrunn forest position	Rear Bavarian Forest	The (former) geological demonstration object in the Bavarian Forest National Park consists largely of buried granite in which sackcloth gneiss clods are embedded. The pit is almost completely overgrown and therefore the exposure conditions are now relatively poor. Clearly visible, however, are the firmer granite parts, which weather like a sack of wool from the more strongly decomposed crystalline gravel.	300 30 × 10	Type: Rock type, wool sacking Type: Granite, crystalline gravel , gneiss	Gravel pit / sand pit	significant	National park, landscape protection area, FFH area
Outcrops between Innernzell and Mutzenwinkel		272A007	Innernzell position	Front Bavarian Forest	The transformation of pearl gneiss into granitoid anatectic rock (palitic rock) is here in places opened up over a longer stretch of blocks and pending. Various phenomena can be seen: pegmatoid streaks, the whereabouts of relict clods of gneisses, amphibolite bodies. The best outcrops are directly north of Innernzell (west of the bridge).	6000 300 × 20	Type: rock type, contact, metamorphic structure Type: gneiss, anatexite, mylonite	embankment	significant	Natural park
Rost quarry on Hartberg N of Thurmansbang		272A010	Thurmansbang position	Passau Forest	In the (former?) Granite quarry, granites from the Fürstenstein intrusive area were mined. This is where the so-called Saldenburg granite occurs, a porphyry granite with tabular potassium feldspars. In this quarry, the otherwise coarse-grained base material is somewhat smaller-grained, unlike the main type. Road building materials such as paving stones and curbs, as well as boundary and stone stones were made from the granite. Weathering profiles are exposed in the edge area.	25000 250 × 100	Type: rock type, soil profile type: granite, granodiorite, granite gravel	Quarry	significant	Natural park
Road outcrops N from Garham (upgraded route B12)		272A012	Röhrnbach position	Passau Forest	The two road cuts (new line B12) cut Mylonite south of the pile line. In the northern outcropping, palites with different degrees of deformation are exposed, which are penetrated by a granite dike (deformed to flame granite). In the southern section through the dust hump, the rocks are less deformed. Metatectic gneiss with amphibolite clods penetrated by numerous passages are exposed there.	2500 500 × 5	Type: rock type, metamorphic structure, fault type: mylonite, gneiss, aplite	embankment	precious	Landscape protection area, nature park
Sand pit near the Brennfilz SW from Haidmühle		272A013	Frauenberger and Duschlberger forest position	Rear Bavarian Forest	Haidmühler granite opens up the small sand pit, which apart from a few rounded bodies is decomposed by weathering and can be broken down as sand. However, the rock is still in the bond, so that the structural features have not been lost. Vertical structures (e.g. crevices, passages) only bend upwards in the direction of the slope. This hooking is due to soil flow in the permafrost soil during the cold periods.	100 10 × 10	Type: rock type, solifluction phenomenon, soil profile type: granite gravel , granite	Gravel pit / sand pit	significant	Landscape protection area, FFH area, nature park
Road outcrops on the St2132, NE of Grüb		272A014	Grafenau position	Rear Bavarian Forest	On the state road west of Grafenau, the northern edge of the shear zone of the Bavarian pile is exposed. The cordierite-sillimanite-potassium feldspar-gneiss varieties are tectonized differently: partly proto- to ultramylonitic, partly hardly deformed, partly cataclastic. In addition to metatectic streaky structures with leukosomes, there are also massive, granular structures. The massive, grainy cordierite-sillimanite-potassium feldspar gneisses are mostly rich in quartz or silicified, often also cataclastically overprinted, their weathered surfaces show a characteristic pearly appearance that is not recognizable in the fresh break. Again and again, cm to dm thick ultramylonites appear. In places, dm-thick, light-gray quartz-gneiss banks have been preserved as spared areas in mylonitized gneiss as well as dm- to m-sized calcium silicate rock layers and boudins. Thin layers of leucocratic gneisses with biotite garnet aggregates are rare.	4000 400 × 10	Type: rock type, fault, metamorphic structure Type: mylonite, ultramylonite, gneiss	embankment	significant	Landscape protection area, nature park
Rocks at Hirschthalmühle on the Große Ohe		272A017	Spiegelau position	Rear Bavarian Forest	To the west of the bridge on the Große Ohe, Orthogneiss is exposed several times on the path leading up to Oberkreuzberg. The fine to medium-grained rocks show a tight layer structure of quartz-feldspar and biotite-rich layers. Zircon dating of neighboring occurrences indicates a sub-ordovician age of the igneous parent rocks. The rock clearances are southwest of the path, where the orthogneiss forms a distinct rib. The foliation dips in a northerly direction. The intensely folded rock appears only slightly fissured in a north-south direction. To the east of the bridge, an orthogneiss ridge that breaks off sharply to the south runs up the slope over a length of about 80 m, which, despite its walls of up to 6 m high, is difficult to see from the path. Here, in places, sharply developed contacts are open. The mostly homogeneous orthogneiss is interspersed in this area with quartz-feldspar streaks (presumably leucosomes) up to 1.5 m thick and gneiss clods.	3000 100 × 30	Type: Metamorphic structure, type of rock, rock wall / slope, fold / trough / saddle Type: Gneiss	Slope crack / rock wall	precious	Landscape protection area, nature park
Mylonite profile in the street cut W of Grafenau		272A018	Grafenau position	Rear Bavarian Forest	On the state road St2132 is one of the best profiles through the shear zone of the Bayer. Stake with various tectonites and the transition from ultramylonites to dark diatexites. The profile includes from S to N rocks of the Palit complex, granite and gneisses, the different. Show deformation types: from hardly deformed to protomylonitic to ultramylonitic, as well as z. T. cataclastic. The road cut consists of two large outcrops, up to 30 m high, separated by a WE-oriented depression. In the N-part there are brownish to reddish, alternately strongly diaphthoritic mylonites, whose light color and porphyroclastic structure indicate a granitoid parent rock. The Mylonitic foliation falls steeply to Saiger after NNW or SSW. After S, the rock is more compact and massive due to secondary silicification, with a few cm thick, spindle-shaped stretched to ribbon-like quartz lenses, accompanied by hydrothermal reddening. Again and again a few dm-powerful ultramylonitic zones occur.	0 not specified	Type: Metamorphic structure, fault Type: Mylonite, Ultramylonite, Migmatite	embankment	precious	Landscape protection area, nature park
Outcrop on the Wolfsteiner Ohe below Fürsteneck Castle		272A019	Fürsteneck position	Passau Forest	There are several outcrops of migmatic gneiss (light diatexite), which contain characteristic clods of dark metamorphic rocks, directly on the road below Fürsteneck Castle (Triftsteig hiking trail).	100 50 × 2	Type: metamorphic structure, rock type: migmatite	embankment	precious	Landscape protection area, FFH area, nature park
Grübenfeld Grüben am Rachel		272G001	Sankt Oswald-Riedlhütte position	Rear Bavarian Forest	The small-scale surface forms of this pit field with pits, ditches and elongated and conical hills go back to anthropogenic activity. Historical sources indicate the exploitation of a soap gold deposit. However, quartz pebbles may also have been extracted later for the nearby glassworks.	120000 400 × 300	Type: Soap laundry, Pinge / nfeld Type: Gravel	no information	significant	National park, ground monument, landscape protection area
Quartz mining pits on the Katzberg		272G002	Neuschönau position	Rear Bavarian Forest	From 1803 to 1874, quartz was extracted in the pits as a raw material for the surrounding glassworks (REINER et al. 1995). The pits are 80 m east of a signposted hiking trail on the Katzberg, but can only be recognized through the slopes of the heaps and some rock clearances in the cordierite-sillimanite-potassium feldspar gneiss. There are a total of 5 abandoned pits of up to 35 × 15 × 9 m in size. Some of the imposing trenches are up to 5 m deep and 25 m long. There is no information in the vein quartz mined here, but the quartz is found as reading stones in the surrounding heaps. The side rock (cordierite-silimanite-gneiss) is exposed in small cliffs and blocks. The numerous quartz fragments that can be found in and around the pits are white to gray-white in color, hardly any feldspar and few adjacent rock fragments. The pits consist of what is now a funnel-shaped mining area and the extensive dumps in front of it. They are important historical evidence of regional raw material extraction.	20000 200 × 100	Type: Pinge / nfeld Type: vein quartz, cordierite-sillimanite gneiss	Ping	significant	National park, landscape protection area, FFH area
Gold washing area near Riedlhütte (Grübenfeld)		272G003	Sankt Oswald-Riedlhütte position	Rear Bavarian Forest	Pit fields as they are z. B. occur here on the southern edge of the Great Felt, are the remains of a former gold mining. The gold was obtained from enrichment zones, the so-called soaps, in the area of river deposits. For this purpose, the gold-bearing gravel had to be washed out. What remains are characteristic terrain forms such as funnel-shaped pits and trenches, mostly in connection with canal systems. A gold washing area was set up by the community on this grave field.	50000 500 × 100	Type: Soap Laundry Type: Gravel	Ping	significant	National park, ground monument, landscape protection area
Medieval melting furnace in Hochbuchet SE von Saldenburg		272G004	Saldenburg position	Passau Forest	There is a trench more than 50 m long and 5 m deep in the forest, but no heaps. The outcrops show an approx. 3 m thick, very fine-grained rhyolite vein (alkali aplite) in coarse-grained Saldenburg granite. Most of the material is said to have been used more recently for ballast production for the expansion of the B85. In addition to the dismantling, an old kiln was excavated, the interior of which is made of rhyolite. The firing temperatures were so high that the rock was melted. By means of a C14 analysis, the operating time of the furnace could be dated between 1280 and 1460. It will not have been a glass furnace, as no glass remains were found in the vicinity. However, there is a presumption that it was a frying furnace in which the coarse mixture of flux, lime and quartz was sintered prior to glass production. The furnace of an alchemist is also suspected.	250 50 × 5	Type: ironworks / smelting furnace, type of rock, scraping type: rhyolite, granite	Schurf	precious	Natural park
Grübenfeld on the Cold Vltava		272G005	Frauenberger and Duschlberger forest position	Rear Bavarian Forest	The well-preserved Grübenfeld stretches from the Kiesau over the Marderau to the Gruben site for 2.5 km along the Cold Vltava. The historical traces of gold mining are referred to as pit fields, which leave a restless relief of funnel pits, trenches, hills, gullies and moats in the landscape. They testify to the washing out of gold flakes from the river sediments (gravel, sand). Quartz gravel was later extracted from these areas.	1000000 2500 × 400	Type: Soap Laundry, Pinging Field Type: Gravel, Sand	no information	precious	Soil monument, nature park
Abandoned mine on Redelberg		272G006	Schönberg position	Rear Bavarian Forest	The mine near Rendelmoos is already mentioned by Flurl (1792) as abandoned and derelict. From around 1580, the search for silver, copper and lead in the pile quartz was unsuccessful. The buried mouth hole with a dump in front of it was located in 2001 by ENE Hartmannsreit am Redelberg.	0 not specified	Type: Adit Type: Vein mineralization	Tunnel / gallery / shaft	significant	Landscape protection area, nature park
Schrazlgang under the Klessinger inn in Hundsruck		272G007	Saldenburg position	Passau Forest	The Schrazlgang in the basement of the inn is open to the public. Its exploration is explained with photos, plans and a video. First mentioned in a document in 1449, the Erdstall is said to be around 1000 years old. The corridor in the weathered Saldenburg granite shows discoloration from iron heels on crevice cracks or along weathered fronts. The Schrazlgang is recorded as a ground monument (medieval - early modern earth stable) (monument no. D-2-7246-0158).	0 not specified	Type: Rock Cellar Type: Granite	Rock cellar	precious	Soil monument, nature park
Funnel pits and pit field for gold mining near Eisenbernreut		272G008	Perlesreut position	Passau Forest	Extraction pits and soap mounds in a forest along the Eisenbernreuter Bach are traces of what is believed to be medieval gold mining. A residual gold soap was cultivated and washed out - an originally primary gold mineralization enriched by profound weathering in a Moldanubian diatexite. The angular gold grains that were washed here have practically not been transported. The property is under special protection as a ground monument (monument no. D-2-7246-0160).	250000 500 × 500	Type: Soap laundry, Pinge / nfeld Type: Gneiss gravel	Ping	precious	Soil monument, landscape protection area, nature park
Blockstrom Gsteinet E from Waldkirchen		272R001	Waldkirchen position	Passau Forest	The boulders were mostly exposed postglacial through spring streams and rainwater emerging in the area.

Buchberger Leite NE from Buchberg	more pictures	272R003	Hohenau position	Passau Forest	Over a length of approx. 2 km, in the middle of a canyon-like, over 100 m deep valley, one of the most beautiful outcrops through the Bavarian pile can be found: various stages of mylonitization, from largely undeformed to ultramylonite, are exposed. In the Buchberger Leite it is easy to understand that the Bavarian stake does not always have to be quartz and that it can have very different morphological effects. The large number of waterfalls is striking.	1000000 5000 × 200	Type: ravine, fault, layer sequence Type: cataclasite, granite, vein quartz	Impact slope / river bed / stream profile	precious	Landscape protection area, FFH area	Bavaria's most beautiful geotopes No. 26

Pulpit in the Bavarian Forest National Park by Glashütte	more pictures	272R013	Hohenau position	Rear Bavarian Forest	The summit cliff is located on a hiking trail and serves as a lookout point. The result of Pleistocene erosion processes is mattress weathering, which the coarse-grained, fibrous orthogneiss shows. The flat blocks and plates correspond to the fracture and fibrous rock structure. There are also some cellular honeycomb weathering structures on the NE side.	320 40 × 8	Type: Ridge Type: Gneiss	Rock slope / cliff	significant	National park, natural monument, landscape protection area
Kleinalmeyerschloss NW of Mauth		272R014	Schönbrunn forest position	Rear Bavarian Forest	The formation of these steep granite cliffs is the result of increased Pleistocene erosion in the periglacial area. Weakly textured structure and platy segregation of the crystal granite lead to mattress-like weathered bodies. The cliffs can only be reached via abandoned paths (core area of the national park!).	1000 50 × 20	Type: rock castle, wool sack formation Type: granite	Slope crack / rock wall	precious	National park, natural monument, landscape protection area

Sea of blocks on the Lusen	more pictures	272R016	Neuschönau position	Rear Bavarian Forest	The entire summit area of the Lusen is a large exposed sea of boulders. This largest sea of boulders in the Bavarian Forest National Park was created by the Pleistocene erosion of the weathering bark and the decomposition of the surrounding rock (fine to medium-grain granite), mainly through frost weathering. The blocks in the upper area disintegrated on the spot, without any major transport down the slope. In this way, corridors can be traced across the sea of blocks.	200000 400 × 500	Type: Blockmeer Type: Granite, Gneiss	block	especially valuable	National park, landscape protection area, FFH area	Bavaria's most beautiful geotopes No. 32

The rock ridge runs roughly in an east-west direction. In the east, the rocks consist almost exclusively of gray to beige-gray quartz vein breccia of the Bavarian pile, which is quite compact despite its narrow fissures due to secondary silicification. In the W, the rock ridge consists mainly of ultramylonite, which is heavily silicified or interspersed with sharply defined quartz streaks. The outcrop is accompanied by pile slate in the north, and old mining in ultramylonite (whet slate?) On the SE edge. A small quarry (quartz quarry) is located on the signposted historical hiking trail of the Ringelai community.	8800 110 × 80	Type: hard rock, rock dome, quarry / pit Type: vein quartz, ultramylonite	Rock slope / cliff	significant	Landscape protection area, nature park

In the east there is an open raised bog area, in the west part is wooded (afforestation and bog forest). At the edges of the peat pit, up to 2 m high peat profiles can be seen.	200000 500 × 400	Type: raised bog, type of layers : peat	Open pit	significant	Landscape protection area, FFH area, nature park
Rock hiking area in the Bavarian Forest National Park W of Mauth	more pictures	272R031	Schönbrunn forest position	Rear Bavarian Forest	In the area of the rock hiking area in the Bavarian Forest National Park, the entire area around the Kleine Kanzel is littered with gneiss cliffs and blocks. South of the Kleiner Kanzel on the hiking trail is a beautiful outcrop in heavily crinkled metatectic to anatectic cordierite gneiss with inclusions of calcium silicate rock. Today's morphological appearance is the result of the Pleistocene erosion of the weathering cover and the associated rock exposure.	1000 50 × 20	Type: group of rocks, type of rock, metamorphic structure Type: cordierite-sillimanite-gneiss, calcium silicate rock	Rock slope / cliff	significant	National park, landscape protection area, FFH area
Diorite cliffs on Garsleite SE von Kollberg		272R032	Röhrnbach position	Passau Forest	Almost all of the numerous diorite cliffs in the forest have an oriented, sloping structure of dividing surfaces into the slope. The dark diorites show light feldspar crystals and biotite nests in a fine-grained to dense matrix. Numerous bright aplites as corridors or irregularly shaped bodies have penetrated the rock both concordantly and discordantly.	12500 250 × 50	Type: Group of rocks, type of rock, storage conditions Type: diorite, aplite	Slope crack / rock wall	precious	Landscape protection area, nature park
Stelzerbach NE of the Stelzermühle		272R033	Waldkirchen position	Passau Forest	Below the street to the Stelzermühle you can see a classic meandering loop of the Stelzerbach. On the rebound slope at the entrance to a side stream, a soil profile is exposed through the tertiary / quaternary weathering cover above the crystalline. Above completely decomposed crystalline there is a layer of rubble as well as sand and clay in which crystalline chunks swim. The formations are intensely colored yellow. To the north the stream shows many meander loops.	200000 2000 × 100	Type: Meander, impact slope, soil profile Type: Crystalline gravel, sand, clay	Impact slope / river bed / stream profile	significant	Landscape protection area, FFH area, nature park
Summit cliff High Saxony W of Grafenau		272R034	Grafenau position	Passau Forest	The summit of the High Saxony is formed by a summit cliff made of granitic-granodioritic dark diatexites with large potassium feldspar crystals with almost vertical walls. At the bottom there is a block field. Today's morphology is the result of Pleistocene erosion during which the tertiary weathering cover was removed and more compact rock areas were exposed. The rock cliffs and blocks are heavily overgrown throughout.	240 30 × 8	Type: rocky dome, sea of rocks Type: migmatite	Rock slope / cliff	precious	Landscape protection area, nature park
The Wolfsteiner Ohe flows into the Ilz near Fürsteneck		272R035	Fürsteneck position	Passau Forest	Narrow gorge with exposed rocks, easily accessible by hiking trails. A light-colored diatexite is exposed that contains metabasite clods and is penetrated by a dacite duct. A younger rhyolite dike is also exposed at several points along the way.	10000 200 × 50	Type: gorge, rock wall / slope, contact type: anatexite, dacite, rhyolite	Impact slope / river bed / stream profile	precious	Nature reserve, landscape protection area, FFH area
Rocks at the Steinbühl summit S of Neudorf		272R036	Grafenau position	Passau Forest	In the summit area of the Steinbühl there is a rib made of Palit, which has disintegrated into a small sea of blocks. The summit itself is formed by a rocking stone created by the weathering of wool sacks. The Palit is extremely mylonitized, which is partly easy to recognize from the blocks.	1000 50 × 20	Type: hardness, block sea, wool sack formation, metamorphic structure Type: gneiss	Rock slope / cliff	precious	Natural park
Erdstall (Schrazelgang) in Waldkirchen		272G009	Waldkirchen position	Passau Forest	Immediately next to parking lot P3 (Jandelsbrunner Straße) in Waldkirchen there is an earth stables, which was discovered in the construction of the parking lot and partially destroyed in the process. The two remaining parts are the rearmost parts of the entire system, which originally consisted of three side arms (Fig. 4, from: The Erdstall 13) They were hand-cut in the heavily buried Hauzenberg-Hutthumer granite without heavy equipment, which can be seen particularly well on the face of the left arm (Fig. 3). The total length preserved is about 16 meters. Further Erdststall, they are also known as Schrazelgang, are located in the urban area of Waldkirchen. However, these are only accessible via the cellars of private houses. The property at parking lot P3, on the other hand, is accessible to everyone as part of city tours. Information about the building office in the town hall (Rathausplatz 1) or the city archive in the community center (Ringmauerstraße 14). Both the exact time of construction and the actual purpose of the systems have not yet been clarified with certainty. The geotope is under special protection as a ground monument (monument no. D-2-7247-0188).	16 16 × 1	Type: rock cellar Type: granite, granite gravel	Rock cellar	precious	Soil monument, nature park
Ochsenfels W of the Saußmühle		272R037	Waldkirchen position	Passau Forest	The rock clearance Ochsenfels am Saßberg near Saußmühle consists of solid, medium-grain Hauzenberg-Hutthumer granite. The rock face is officially used as a climbing rock. Since the Ochsenfels plateau has a late medieval castle stables, the ditch of which is still very well preserved, the area is under special protection as a ground monument (monument no. D-2-7247-0021).	450 15 × 30	Type: Rock Tower / Needle Type: Granite	Rock slope / cliff	precious	Soil monument, landscape protection area, nature park
