Hiking

In this small quarry, serpentinite, known as "Schwarzer Kies" (Black Gravel), was formerly mined for road and railway ballast. The occurrence of this ultrabasic rock (very rare in the Bavarian Forest) within the gneisses is presumably linked to imbrications from greater depths in the area of shear zones. The former gravel pit now serves as a geological exhibit in the National Park. The serpentinite imbrication continues on the opposite side of the road.

The quarry had a rail connection to the Spiegelauer Waldbahn. With a stone crusher, the stones blasted from the rock were processed on-site into gravel, loaded onto box wagons, and transported to the new construction lines.
