The Morillon cliffs

Cleared by the Lemme, which has formed a wind gap here, the Morillon cliffs are a succession of vertical strata comprised of hard limestone ledges and marlstone layers that are more sensitive to erosion. This is a great location for a lesson in Jura geology: these sedimentary rocks were created around 200 million years ago, and their folds were created due to the mountain pressure between 11 million to 3 million years ago. Exposed by a geological cut, these layers are very visible and this site - which is now open to experienced climbers - is equipped with an interpretive signpost providing information of how this landscape came to exist.
