It was deposited mostly between ~64.5 and ~61 million years ago, during the early and middle Paleocene. The climate was humid and warm to hot. This unit interbeds with the
Trödelsteine (rock formation) 10.2-kilometre-long branch of the Rothaarsteig. The E1 European long distance path runs over the mountain, crossing the road at the state border.

Also running past the rocks are the Heller Ridgeway ("Hellerhöhenweg", waymark "H") and Siegerland High Ring ("Siegerland-Höhenring").
