The "pancake rocks" are located near "Chockstone Ridge" on the Shipyard-Titanic hiking trail (trail brochure here http://www.wnms.ca/wp-content/uploads/2019/10/shipyardoct2019.pdf )in the Tumbler Ridge UNESCO Global Geopark. The Geopark has many signs along its hiking trails providing geological information describing the area hikers enjoy.
Babcock Mountain is capped by a thick layer of coarse-grained sandstone and conglomerate, once laid down in a high energy fresh-water environment in the Cretaceous Period. Beneath this layer are many other, older layers, some of them composed of softer siltstone or softer-still kaolinite, a type of clay . During the building of the Rocky Mountains, the rock layers of the mountain were subjected to immense forces and became tilted at an angle of about 15 degrees to the horizontal. At some point the top layers including the thick sandstone slid down along this layer of kaolinite (geologists call this “translational movement”) and slowly slid off the edge of the mountain in many places. This thick layer of sandstone came to rest, creating facinating rock structures like the Armada, Chockstone Ridge, Bismark, and the Titanic.
