List of geotopes in the Altötting district

This list contains the geotopes of the Upper Bavarian district Altötting in Bavaria . The list contains the official names and numbers of the Bavarian State Office for the Environment (LfU) as well as their geographical location. This list may not be complete. Around 3,400 geotopes (as of March 2020) are recorded in the Bavarian geotope register. The LfU does not consider some geotopes suitable for publication on the Internet. For example, some objects are not safely accessible or may only be entered to a limited extent for other reasons.

Nagelfluh outcrop W from Mankham		171A005	Feichten at the Alz position	Inn region	In the 8–12 meter high wall, geological organs are formed in the Mindel gravel, which are cut off by crack gravel. In the crack gravel, clods of older soil formation (from the Mindel-Riss interglacial) can be seen.	1900 95 × 20	Type: Fossil Soil, Layer Sequence, Geological Organ Type: Conglomerate	Quarry	precious	no protected area
Former Nagelfluh break W of Unghausen		171A006	Mehring position	Inn region	The boundary between the conglomerates with finer components of the Günz advance gravel and the overlying conglomerates with coarse components of the Günz moraine is clearly visible on the former walls of the small quarry. The former Nagelfluhbruch has partially collapsed. In the meantime the quarry was completely filled and renatured. In 2012 the geotope was released again.	150 15 × 10	Type: Layer sequence Type: Conglomerate	Quarry	precious	no protected area
Dachlwand NW from Marktl		171A007	Perach position	Isar-Inn hill country	Before the Inn cut even deeper, the Dachlwand northwest of Marktl was an impact slope. The rock wall with caves and earth pillars consists of former debris from the Alps, so-called molasse rocks. This rubble was deposited during the uplift of the Alps in the Tertiary period. The location is significant in terms of scientific history, as part of the structure of the Upper Freshwater Molasse (southern gravel) was researched there.	120000 800 × 150	Type: standard / reference profile, impact slope, ravine, rock type: conglomerate	Slope crack / rock wall	especially valuable	Nature reserve, landscape protection area, FFH area
Salzach-Prallhang near Burghausen		171A008	Burghausen position	Inn region	At Burghausen the Salzach cuts up to 50 meters deep into the ground. Tertiary and Quaternary rocks are exposed on the steep bank walls. The tertiary (molasses) is represented by the southern full gravel and the hanging series. This is followed by Quaternary gravel from the Riss and Würme Ice Age as high and low terraces. Rock falls are formed on the eastern Austrian bank as a result of the undercut by the Salzach.	24000 600 × 40	Type: layer sequence, impact slope Type: conglomerate, sandstone	Impact slope / river bed / stream profile	precious	Natural monument, landscape protection area, FFH area
Salzach-Leite near Raitenhaslach		171A009	Burghausen position	Inn region	On the Salzach slope below the monastery grounds, landslides have created individual outcrops. Sandstone banks and brown coal seams can be found in the Upper Freshwater Molasse. However, the outcrops decay and grow together relatively strongly.	2000 200 × 10	Type: Layer sequence Type: sandstone, brown coal	Slope crack / rock wall	significant	Natural monument, landscape protection area, FFH area
Isen-Prallhang NE by Aresing		171A010	Töging at the Inn position	Inn region	Rocks from the Upper Freshwater Molasse are exposed on the Isen slope. Basal gravels are overlaid by sands containing a lot of mica, almost pure mica layers, marl inclusions and a silty layer of fine sand with remains of leaves. The so-called cornice sands or cone sands form a geological peculiarity: hard, exposed layers and cones made of carbonate solidified sands, which protrude up to 1.5 meters as roofs and protrusions from the exposed wall.	6500 130 × 50	Type: sedimentary structures, impact slope, rock type, vegetable fossils Type: sand, gravel	Impact slope / river bed / stream profile	especially valuable	no protected area
Conglomerate fracture S from Hinterberg		171A011	Kastl position	Inn region	In the quarry Nagelfluh the younger gravel from the Mindel glacial period was mined. The traces of sedimentation, some of which are slightly sloping, from the sands of draining glaciers are easy to read.	4000 200 × 20	Type: sedimentary structures, rock type: conglomerate	Quarry	precious	no protected area
Abandoned conglomerate fracture SW of Gerlhof		171A012	Kastl position	Inn region	Abandoned Nagelfluh quarry. The semicircular remains of the geological organs (vertical solution forms) can be seen along the dismantling walls. Traces of sedimentation in the inclined stratification of fine material, especially sand, indicate deposits on the edge of a flowing water. Occasional drill marks testify to rock mining.	6000 300 × 20	Type: geological organ, sedimentary structures, rock type: conglomerate	Quarry	significant	no protected area
Riser pressure well in Bergham		171G001	Marktl position	Inn region	The approximately 200 m deep borehole was previously used to supply gas to the Altenbuchner inn. A gasometer was pushed up on rails by the gas pressure. However, no more gas has been extracted since around 1970, and the inn has been abandoned since 2012. The gas storage facility is in great need of renovation. Below the former conveyor system, the water still emerges from the borehole at around 2 l / s artesian. The water contains iodine and was used for the adjacent house. The container from which the water exits was the pressurized water container for a hydraulic ram below, which pumped the water upwards. The facility is located on private property. Get the owner's permission before entering!	9 3 × 3	Type: Bore Type: Conglomerate	no information	significant	no protected area
Lime kiln W from Steinfelder		171G002	Marktl position	Inn region	The well-preserved lime kiln from 1884 in a typical hillside location with a firing hut and conical, partly underground kiln is the only completely preserved structure in the district, the ruins of another lime kiln near Unterhadermark / Burghausen (Haigermoos) were renovated in 2017. In the past, limestone (calcium carbonate) from the surrounding post-glacial terrace gravel of the Alz and other rivers was burned in the lime kilns to make quicklime (calcium oxide). After adding a little water, it served as slaked lime (calcium hydroxide) as wall paint or fertilizer or, after adding a lot of water and sand, as (lime) mortar.	50 10 × 5	Type: Lime Kiln Type: Limestone, Gravel	no information	significant	no protected area
Bear Cave SE by Altwies		171H001	Marktl position	Isar-Inn hill country	The roof of the cave is built from conglomerate full gravel. The cave was created by erosion from episodic spring outlets. At the entrance there is an anthropogenic vessel made from Nagelfluh, carved out of what is standing.	30 10 × 3	Type: Eruption / Weathering Cave Type: Conglomerate, Gravel	cave	significant	Nature reserve, FFH area
Geological organs rugged	more pictures	171R001	Untereukirchen position	Inn region	The quarry in the younger gravel was used to mine the Nagelfluh. The former demolition walls are traversed by vertical, tubular solutions - so-called geological organs. The latter were created before / during the solidification of the rock and are uniquely well developed in Oberschroffen in Bavaria. The chimney-like tubes have a diameter of about half a meter, are partly filled with clay, cut into sections or allow a view through the rock.	7200 120 × 60	Type: Geological Organ, Fossil Soil, Quarry / Pit Type: Conglomerate	Quarry	especially valuable	Natural monument	Bavaria's most beautiful geotopes No. 82
