Peter Seroka has addressed the issue in several years of work and has written an up-to-date geological summary. He dedicated his work to the 15 th anniversary of Mineralienatlas.

Nevertheless, in the past, evil itself is said to have preached to the damned here from a large, solitary, towering rock spur. Today, the term Devil's Pulpit inspires one to play with associations, as do the drawings of agates found here.
