Devil's Wall in the Evening
by David Tanner, Leibniz Institute for Applied Geophysics (LIAG), Hannover, Germany
The Devil's Wall in Germany (Teufelsmauer) is composed of Cretaceous sandstones that were folded and raised into a vertical position by inversion on the Harz north boundary fault. Immediately after obtaining this position, they were intensely silified by fluids and became very hard. Thus the wall has remained after all the weaker surrouding sediments were eroded. The bizarre formation is even better at sunset. The name comes from local legends about how the wall came to be.
