Description

Morphology

The Dörenthe sandstone (Osning sandstone, Lower Albian, Lower Cretaceous) geotope "Varusfelsen" and "Fledermaushöhle", protected as a natural monument, consists of rock ribs naturally formed by weathering, 20 m wide and up to 40 m long. The medium-grained, massive to thickly bedded sandstone shows partial cross-bedding and conglomerate layers. The bedding dips at 176/62 degrees toward the south. Occasionally ripple marks can be observed on the bedding surfaces. Characteristic are idiomorphic quartz grains, which on weathered surfaces produce a rough surface as small angular grains. The Fledermaushöhle is hard to access and appears to be only 1.5 x 1.5 m in size.

Other details

The rock group is well accessible via hiking trails.
