Former quarry E of Kleinrampsau		375A001	Regenstauf position	Regensburg Forest	Quartz porphyry was mined in two adjacent quarries. The quarry floor is strongly overgrown and difficult to access due to fallen granite blocks.	700 20 × 35	Type: Rock Type: Rhyolite, Granite	Quarry	significant	Landscape protection area
Former quarry on Schellerberg near Regenstauf		375A002	Regenstauf position	Regensburg Forest	The large quarry has an irregular quarry wall that opens up a Pinitporphyry tunnel with 2 ointment bands. The rock of the Pinitporphyry Dike is much more weathered than the surrounding granite.	2000 50x40	Type: Rock Type: Rhyolite, Granite	Quarry	significant	Landscape protection area
Rocks in Wulkersdorf		375A003	Bernhardswald position	Regensburg Forest	Folded ribbon gneisses are exposed within a farm. The light layers consist of quartz, potassium feldspar and plagioclase, the dark layers of biotite with garnet inclusions. The characteristics are clearly pronounced.	250 25 × 10	Type: Type of rock Type: biotite, plagioclase, gneiss	Slope crack / rock wall	precious	no protected area
Former quarry W of Plitting		375A004	Bernhardswald position	Regensburg Forest	The blastomylonite, garnet-bearing grain gneiss shows numerous orthoclase inserts up to 12 cm long (Carlsbad twins). The former quarry is almost inaccessible and filled with rubbish. The features described can hardly be recognized.	6 3 × 2	Type: Rock Type: Blastomylonite	Quarry	significant	no protected area
Former quarry on Mühlberg SW von Hauzendorf		375A005	Bernhardswald position	Regensburg Forest	In granodioritic granular gneiss there are lentils from banded gneiss and paragneiss clods as well as some basic inclusions.	200 10 × 20	Type: Rock Type: Gneiss	Quarry	significant	no protected area
Former quarry SE from Beratzhausen		375A006	Beratzhausen position	Middle Franconian Alb	In the former quarry at the southern entrance to Beratzhausen, a sponge reef of the Lower Franconian Alb formation is cut. Partly clear layered joints and some noticeably thin banks trace the structure of the reef dome. These closely spaced layers are likely to correspond to the lower marl plate, which also occurs in the banked and calcareous Treuchtlingen formation (Malm Delta). There is currently no evidence that the area under the thin-banked layers could be Malm Gamma - see MEYER & SCHMIDT-KALER 1983: Geological Guide through the Altmühlalb.	3000 150 × 20	Type: sedimentary structures, rock type: dolomite stone	Quarry	significant	no protected area
Niebler E quarry from Hennhüll		375A007	Hemau position	Southern Franconian Alb	The eastern of the former two quarries near Hennhüll is still relatively well preserved. Approx. 15 m of slab and bench limestone has been developed. The bench limestone inserted between the plate limestone consists of 6 horizons of so-called crooked layers as well as rubble limestone and Breistein banks. This form of the Painten formation is called the Hennhüll subformation. Even if the walls slowly collapse and numerous bushes block your view during the vegetation period, this outcrop is still in a very good condition overall, so that not only the walls are still open, but also the stratified surfaces can be seen over long stretches where the respective excavation floors have been created.	5000 100 × 50	Type: Type locality, rock type, sedimentary structures Type: Limestone	Quarry	precious	no protected area
Former quarry on Hütberg near Deuerling		375A009	Deuerling position	Middle Franconian Alb	The western rocky slope of the Hütberg is mostly only indistinctly banked, but two banks can be seen that could correspond to the lower and upper marl slabs. The Treuchtlinger marble lies here in a small layer facies tub within the Parsberg reef range.	800 40 × 20	Type: Layer sequence Type: Limestone	Quarry	precious	Landscape protection area, FFH area, bird sanctuary
Climbing rocks of Schönhofen	more pictures	375A010	Nittendorf position	Southern Franconian Alb	A thin band of banked Epsilon dolomite is open above the gray delta dolomite walls. Above it lies a white wooden dolomite from the Upper Malm. The rock walls on the slope of the Schwarzen Laaber are used as a climbing area.	5000 250 × 20	Type: Sequence of layers, rock wall / slope Type: Dolomite stone	Slope crack / rock wall	precious	no protected area
Former opencast mine NW of Kittenrain		375A011	Bach on the Danube position	Regensburg Forest	In the past, the Kittenrainer Fluorspargang was surface mined here. Outcrops in the adjacent rock (granite) are still present, remains of fluorspar can be found as reading stones.	200 20 × 10	Type: Minerals , Open Pit Type: Granite, Vein mineralization	Open pit	significant	Landscape protection area
W Quarry at Scheuchenberg SE from Sulzbach ad Donau		375A013	Bach on the Danube position	Dungau	On the south side of the Scheuchenberg there are several former quarries in wine-growing rocks of the Danube fault. The westernmost break is easily accessible and hardly collapses. Here, hydrothermally modified, reddish, fine-grain biotite granites that have been repeatedly tectonically brecciated and healed again with quartz are exposed.	20000 200 × 100	Type: rock type, metamorphic structure, fault type: meta, granite, crystalline breccia	Quarry	significant	Landscape protection area, FFH area
Quarry at Spindelbach ENE von Grünthal		375A014	Wenzenbach position	Regensburg Forest	Inhomogeneous diatexites, which were less affected by homogenization at this point and represent well-foliated biotite-cordierite gneisses, in contact with a fine-grained two-mica granite of the peripheral facies are exposed.	60 12 × 5	Type: Rock type, contact, metamorphic structure Type: Gneiss, granite, migmatite	Quarry	significant	Landscape protection area
Former Quarry Eckl N Bügerl		375A015	Hemau position	Southern Franconian Alb	There is now a shooting range in the former Eckl quarry north of Bügerl. In the still open quarry wall behind it, there are approx. 5 m thick bench limestone of the deeper Painten formation, in which two crooked layers, each approx. 1 m thick, are inserted.	4000 100 × 40	Type: Rock Type: Limestone	Quarry	precious	Natural park
Steep edge in Laubenhartgrund		375A016	Hemau position	Southern Franconian Alb	In the steep ascent on the east side of the Laubenhartgrund there are approx. 10 m of silica limestone and slab silex that have been mined in a small quarry. However, this occurrence (the type profile of the Tangrintel Formation) has largely collapsed and overgrown today, so that only a few places are left. The indication of Malm Epsilon, stratified limestone is to be seen as a makeshift solution, as the correct geology information is not currently stored in the key list	300 30 × 10	Type: type locality, rock type: pebble limestone	no information	precious	Landscape protection area
Former Quarry at Kollerhof SE from Dinau		375A019	Kallmünz position	Middle Franconian Alb	The outcrop is a reference profile of the Ebenwies subformation of the Torleite formation. The indication Malm Epsilon, stratified limestone under Geological Description is incorrect. It was only used because the field is a mandatory field and the correct information Torleite formation or Ebenwies subformation of the Torleite formation is not available in the key lists.	10000 100 × 100	Type: standard / reference profile, layer sequence type: limestone	Quarry	precious	Landscape protection area
former quarry WNW of Krippersberg		375A020	Wolfsegg position	Middle Franconian Alb	Long, sloping quarry in the basal areas of the Regensburg formation (Regensburg green sandstone). The quarry is largely overgrown and dilapidated. In places, however, the green sandstone is still pending. Along the narrow strip of land to the west of the outcrop there are repeatedly plowed-out rocks made of green sandstone with reclaimed plate limestone from the Ebenwies subformation or limestone in the crevices of which green sandstone occurs. These rocks come from the immediate transgression area of the Upper Chalk Sea over the land surface built up by the White Jurassic limestone at that time.	7500 250 × 30	Type: sequence of layers, type of rock type: sand-lime brick	Quarry	significant	Landscape protection area, FFH area, bird sanctuary
Limestone extraction N from Brunn		375A023	Brunn position	Middle Franconian Alb	The plate liming on Zeinberg N von Brunn was carried out for research purposes by Dr. Röper (Solnhofen) and delivered numerous fossils. Röper & Rothgänger (1999) Die Plattenkalke von Bronn provide a compilation of this. Unauthorized entry to the fossil site is not allowed! The tub sediments of Brunn with plate limestone (below) and bench limestone (above) belong to the Ebenwies subformation of the Torleite formation and are a reference profile of this subformation. The Malm Epsilon layered lime specification is a stopgap measure, as the key lists in the BIS have not yet allowed correct allocation.	2500 50 × 50	Type: Animal Fossils, Standard / Reference Profile Type: Limestone	other information	especially valuable	no protected area
Former Sand pit on the Girnitz		375A024	Duggendorf position	Middle Franconian Alb	In the sand pit on the Girnitz, loose sandstone and sands from the protective rock formation were mined for local needs until the 1950s. The unsorted, well rounded quartz sands with a maximum grain size of around 8 mm are partially bound with silicate. These hard parts were not mined and therefore today form small quartzite rocks in the former sand pit, which was unfortunately littered with all sorts of debris. Such quartzites were often to be found on the surface of the Franconian Alb (at least until they were extensively eliminated by the land consolidation). These weather-resistant relic blocks - detached from their original rock structure and not clearly assignable to a parent rock - are commonly referred to as Kallmünzer. The quartzite rocks in the sand pit on the Girnitz are Kallmünzer in the rock and can therefore be assigned to the protective rock formation.	1800 60 × 30	Type: Rock Type: Quartzite, Quartz Sandstone, Sand	Gravel pit / sand pit	precious	Landscape protection area
Former Gneiss fracture on the Refberg NE of Refthal		375A025	Altenthann position	Regensburg Forest	The abandoned quarry on Refberg opens up a granular anatectic biotite gneiss (formed from partially melted granite), which often contains larger inclusions of orthoclase (alkali feldspar) and is therefore also known as granular gneiss. A corridor-shaped diorite deposit was mapped between the parking lot to the west on the St 2650 and the quarry area. It can be proven by reading stones. The pegmatite dikes described by ANDRITZKY (1968) were not (any longer) exposed in the quarry in 2015.	500 20 × 25	Type: metamorphic structure, rock type: gneiss	Quarry	precious	Landscape protection area
Cave castle hole		375A026	Nittendorf position	Southern Franconian Alb	The Höhlenburg Loch is one of only two cave castles in Bavaria (the second is in Stein ad Traun in Upper Bavaria). The lower, flatter part of the castle area lies in the plate dolomites, which are part of the Velburg horizon. The steep wall, at the base of which the (residential) caves appear, is formed by mass dolomites of the Middle Franconian Alb formation.	3600 120 × 30	Type: Type of rock, karst halfway / natural bridge, rock castle Type: dolomite stone	cave	significant	Landscape protection area, FFH area, bird sanctuary
Golden hood		375A027	Beratzhausen position	Southern Franconian Alb	The dolomite of the Frankenalb Formation can disintegrate into its sand-grain-sized, golden-yellow individual crystals in the course of weathering, starting from fissures in the rock. The resulting dolomite sand was previously used for walls in the area of the Alb. When this sand was excavated along the clefts on the golden hood, structures that are reminiscent of walls and rooms were created. This led to two legends according to which the golden hood is said to be the remains of a cursed castle. The massive dolomites of the Frankenalb formation emerged from sponge reefs. Due to the weathering, the contours of these sponges are carved out as hollow shapes. This creates a restless, holey-looking surface of the mass dolomite, which you can see very nicely in the walls of the Golden Dome. Especially in the nooks and crannies of the Golden Dome, the dolomite sands still fill the gaps today, so that you can see very nicely how the massive rock flows smoothly into loose sand.	900 30 × 30	Type: Rock type, crevice, quarry / pit Type: Dolomite stone	Gravel pit / sand pit	significant	Landscape protection area
Former quarry SE von Ebenwies		375G001	Pettendorf position	Middle Franconian Alb	The light limestone (reef rubble limestone of the Upper Kimmeridge) from the former Ebenwies quarry provided the building material for the Walhalla. The broken walls show large areas of drill holes and traces of the wire sawing work with which the limestone blocks were removed from the wall. Romantic overgrown ruins of the earlier factory buildings are still preserved. Stay away from the high break walls! The first major plate limestone development began in the Mittel-Kimmeridge of Ebenwies, the most famous representatives of which are the younger plate limestone of Solnhofen (Unter-Tithon).	800 80 × 10	Type: quarry / pit, layer sequence type: dolomite stone, limestone	Quarry	precious	Landscape protection area, FFH area, bird sanctuary
Former fluorspar mine NW of Kittenrain		375G002	Bach on the Danube position	Regensburg Forest	An approximately 2 m thick and 450 m long fluorspar quartz corridor was excavated after several historical operating periods (documented since 1496) in the so-called Schönfrebs mine (name of the pit since 1703) mainly from 1970 to 1994 and largely dismantled. Purple and light green fluorspar, quartz and chert were extracted. The Kittenrain pit can now be visited as a show mine.	100 10 × 10	Type: Stud Type: Granite	Tunnel / gallery / shaft	significant	Landscape protection area
Former fluorspar mine Sulzbach II		375G003	Donaustauf position	Regensburg Forest	From 1918 to 1960 the mine in the Donaustaufer Fluorsparvier mined a fluorspar dike in granite up to 6 m, later 2 m thick, over three tunnels and a die. Over the course of the day, the corridor was dismantled in a deep dig that extends 200 m up the mountain.	200 100 × 2	Type: tunnels, minerals, layer sequence Type: granite, vein mineralization	Tunnel / gallery / shaft	precious	Landscape protection area, FFH area
Digging pit field SW of Kohlstadt		375G004	Sinzing position	Southern Franconian Alb	The large excavation pit originates from the former mining of stone ore. The countless small hollows and heaps can be seen very well in the area, which is largely free of undergrowth and moss-grown.	180000 600 × 300	Type: Pinge / nfeld Type: Limestone	no information	precious	Ground monument
Pinging at Reichenstetten		375G005	Sinzing position	Southern Franconian Alb	In the 1950s, the Rauhlochschacht, a sloping tunnel through which brown coal was extracted, was located on the northwest edge of Reichenstetten. Today's pinge resembles a sinkhole.	3600 60 × 60	Type: Stollen, Pinge / nfeld Type: Limestone, lignite	Ping	significant	no protected area
Robber's Cave N of Etterzhausen		375H001	Nittendorf position	Middle Franconian Alb	The spacious cave serves as an excursion destination. It has two entrances (located on the rocky slope). The rock inside the cave is z. Sometimes overgrown with lichens.	250 50 × 5	Type: Karst horizontal cave Type: Dolomite stone	cave	significant	no protected area
Bachmühlbach springs at Bachmühle	more pictures	375Q001	Hemau position	Southern Franconian Alb	The source is located on the Swabian-Franconian lineament. The water exits from several deep funnels at the bottom of the stream. The discharge (approx. 100 l / s) is extremely constant for a karst spring.	1750 350 × 5	Type: Source of interference Type: Dolomite stone, limestone	no information	precious	Natural monument, landscape protection area
High rocks N of Beratzhausen		375R001	Beratzhausen position	Middle Franconian Alb	The Hohe Fels north of Beratzhausen is the southwestern flank of a sponge reef from the Lower Franconian Alb formation. Extensive layer joints in the Dolomites, which at first glance appear massive, trace the inclination of the reef flanks to the southwest. About halfway up the high rock, some noticeably thin banks particularly emphasize this collapse. These closely spaced layers should correspond to one of the two marl plates (probably the lower one) that also occur in the banked and calcareous Treuchtlingen Formation (Malm Delta). The Schwarze Laber turns directly in front of the Hohe Fels from the northwest-southeast direction into the northeast-southwest direction. The actual center of the reef is in the south-eastern continuation of the valley.	5000 100 × 50	Type: rock castle, layer sequence type: dolomite stone	Slope crack / rock wall	precious	no protected area
Castle hill in Wolfsegg	more pictures	375R002	Wolfsegg position	Middle Franconian Alb	Wolfsegg Castle stands on a small island mountain, which is bordered on three sides by the Wolfsegger dry valley. In the east it is separated from the actual valley ascent by a shallow depression, which probably corresponds to an earlier valley level. The castle hill is built up from clearly banked dolomite stones of the Pottenstein formation (Bernhof subformation). There is a cave system in the mountain below the castle. This is not open to the public, access is blocked by a barred gate.	2500 50 × 50	Type: rock castle, karst shaft & horizontal cave Type: dolomite stone	Slope crack / rock wall	significant	Natural monument
Kallmünz Castle Hill	more pictures	375R003	Kallmünz position	Middle Franconian Alb	The dolomitized reef complexes of the higher Malm Delta and Epsilon were exposed here in a unique way by Naab and Vils.	60000 300 × 200	Type: Rock wall / slope, sedimentary structures Type: Dolomite stone	Slope crack / rock wall	significant	Landscape protection area, FFH area
Ponor-Doline SE from Neuhof		375R004	Brunn position	Middle Franconian Alb	The sinkhole is connected to the polje of Neuhof - Zeinberg - Wischenhofen via a ditch almost 400 m long. During heavy rain events or when the snow melts in the southern section, a large part of the Polje von Wischenhofen-Neuhof is drained into the subsoil via the sinkhole of this sinkhole. There are more sinkholes, especially in the west and south-west. Just a few meters south of the south wall of the sinkhole, another deep trench begins. This leads to numerous other sinkholes at its bottom and extends to Brunn.	2500 50 × 50	Type: sinkhole Type: dolomite stone	no information	significant	no protected area
Rock wall with cave on Weitzenberg W of Kallmünz		375R005	Kallmünz position	Middle Franconian Alb	In the imposing rock face is a 7 m long cave (location of the cave entrance: R4496438 / H5446826). The cave follows a chasm. The cave ends where the gap has not yet been cleared. The gap is about NW-SE. The wall itself is formed from the widely banked Dolomites of the Bernhof subformation of the Pottenstein formation. The joints between the individual benches are horizontal and do NOT show a domed structure. There are also no areas in which the benches are completely fused and the wall appears to be disorganized. As a first approximation, the wall is built up by three benches with a thickness of several meters. Between these are thinner benches (in the range of 1 m). T. also form fillets. Some of the banks also merge in sections to form a correspondingly thicker bank. Above the rock face, the giant banks z. Sometimes the entire slope is stepped like a staircase up to the striking flattening at about 440 m above sea level. Beneath the wall, too, banked dolomite are repeatedly developed, but the bench strengths rarely exceed 1.5 m.	500 50 × 10	Type: rock face / slope, karst halfway / natural bridge Type: dolomite stone	Slope crack / rock wall	significant	no protected area
Rocks at Eichenberg N of Kallmünz		375R006	Kallmünz position	Middle Franconian Alb	In the SW, the base of the Eichenberg consists of banked Dolomites of the Pottenstein Formation, which repeatedly form smaller pulpits and steps as the slope increases. In the NE it is built up by mass dolomites of the Lower Franconian Alb formation. Above this, with the Velburg horizon, which is only a few meters thick, follows a thin layer package. Above this horizon, the massive, light-colored dolomites of the Middle Franconian Alb formation rise vertically up to 20 m. The thin bank of the Velburg horizon is noticeably different from the thick banked Pottenstein Formation as well as the massive Frankenalb Formation and covers both the banked and the massive facies. Therefore, it is a regionally important key horizon, which is z. B. also allows the Lower Franconia to be separated from the Middle Franconian Alb formation.	60000 200 × 300	Type: rock wall / slope, layer sequence type: dolomite stone	Slope crack / rock wall	significant	Nature reserve, FFH area
Galgenberg near Regenstauf		375R007	Regenstauf position	Middle Franconian Alb	The Jura rock is covered with typical vegetation (dry grass community).

Regenstaufer Schlossberg		375R008	Regenstauf position	Middle Franconian Alb	The incrusted crystal granite has orthoclase fragments with an edge length of up to 10 cm.	1500 50 × 30	Type: Rock Wall / Slope Type: Granite	Slope crack / rock wall	significant	Landscape protection area
Giant jump NW of Drackenstein		375R009	Regenstauf position	Regensburg Forest	The rock formation, also popularly known as the Druid Stone, is said to have served as a thing site at the time of the Marcomanni. It is made of sackcloth granite blocks.	32 8 × 4	Type: Wool Sacking Type: Granite	block	significant	Natural monument, landscape protection area
Kürner Schlossberg		375R010	Bernhardswald position	Regensburg Forest	A broad pinitporphyry corridor forms the foundation of the castle. He is open-minded in rocky areas on the southern slope. The aisle sits in the crystal granite 1 that most of the wool sacks in the park are made of.	10000 100 × 100	Type: rock wall / slope, wool sack formation Type: rhyolite, granite	Slope crack / rock wall	precious	no protected area
Granite rock in Kürn		375R011	Bernhardswald position	Regensburg Forest	There are two large blocks of granite rock piled on top of each other on private property. The typical weathering of wool sacks and feldspar sprinkles are striking.	36 6 × 6	Type: Rock tower / needle, wool sack formation Type: Granite	Slope crack / rock wall	precious	no protected area
Galgenberg SE from Beratzhausen		375R012	Beratzhausen position	Middle Franconian Alb	The table mountain-like rock bastions in the northeast belong to the southwest flank of a reef dome, the actual reef center and the northeast flank are not developed. The banks sloping to the southwest show thicknesses in the meter range, but sometimes also below. The layer surfaces are very clearly developed. The rocks southwest of it (up to the railway bridge) are, in contrast, noticeably rugged with numerous peaks and ridges. This is caused by (at least) two gap or fault directions that cross here. The individual clods between the dividing surfaces are correspondingly bizarre carved out by the weathering.	1600 40 × 40	Type: Rock wall / slope Type: Dolomite stone	Slope crack / rock wall	significant	Natural monument, landscape protection area, FFH area
Rock clearance 1 SSE from Beratzhausen		375R013	Beratzhausen position	Middle Franconian Alb	The rock face northeast of the waterworks in the valley of the Schwarzen Laber is built up by the Dolomites of the Franconian Alb formation. The impressive rock formation of the Jura is surrounded by a species-rich mixed deciduous forest.	1200 60 × 20	Type: Rock wall / slope Type: Dolomite stone	Slope crack / rock wall	inferior	Natural monument
Rock clearance 2 SSE from Beratzhausen		375R014	Beratzhausen position	Southern Franconian Alb	The rock clearance northwest of the waterworks on the Schwarzen Laber belongs to the southwest wing of a reef dome in the dolomite of the Frankenalb formation. There is a small cave at the foot of the northwest wall of the rock exposure. Above the rock formation are three ring walls of Celtic origin.	1000 20 × 50	Type: Rock wall / slope Type: Dolomite stone	Slope crack / rock wall	significant	Landscape protection area, FFH area
Sixenfelsen or Hundstein in Beratzhausen		375R015	Beratzhausen position	Middle Franconian Alb	A sponge reef complex of the Lower Franconian Alb Formation is cut into the steep face along State Road 2294 between the southern entrance to Beratzhausen and the small commercial area. Often indistinct layer joints in the Dolomites, which at first glance appear massive, trace the structure of the reef complex. In the foot area of the rock face and about halfway up, two bands with noticeably thin benches particularly emphasize the flat ups and downs of the layers. These narrow layers are likely to correspond to the lower or upper marl plate, which also occurs in the banked and calcareous Treuchtlingen Formation (Malm Delta). There is currently no evidence of membership in the Malm Gamma (MEYER & SCHMIDT-KALER 1983).	4500 150 × 30	Type: rock wall / slope, layer sequence type: dolomite stone	Slope crack / rock wall	significant	Natural monument, FFH area
Rock summit with Hiaslhöhle S from Beratzhausen		375R016	Beratzhausen position	Southern Franconian Alb	The small, around eight meter high rocky dome of the Hiasl cave is built up by mass dolomites from the Franconian Alb formation. Numerous crevices run through the horizontally poorly structured block. The Hiaslhöhle, a low cave only a few meters long, was created along one of these clefts. Half of the entrance to the cave is built with stones. However, this barrier still allows a view into the small cavity. The name Hiaslhöhle goes back to the fact that a hermit who was called Hiasl lived there from 1924 to 1948.	100 20 × 5	Type: rocky dome, karst horizontal cave Type: dolomite stone	Rock slope / cliff	significant	Landscape protection area

Protective rock NW of Pentling	more pictures	375R032	Pentling position	Southern Franconian Alb	On the Schutzfels (on the eastern bank of the Danube between Schwalbennest and Fohlenhof) the type of locality of the Schutzfels formation is open. The clay-sandy deposits of the protective rock formation lie in a karst hollow form formed in massive limestone in the Lower Cretaceous Period . Since these are easily weathered, a semi-cave has formed in this area, which offers protection from bad weather (hence the name Schutzfelsen). The roof of this half-cave is formed by the green sandstone of the Regensburg formation, at the base of which a transgression conglomerate has developed.	200 20 × 10	Type: rock wall / slope, type locality, sequence of layers, discordance Type: sandstone, limestone, clay	Slope crack / rock wall	especially valuable	Nature reserve, FFH area	Bavaria's most beautiful geotopes No. 56
