Several tracksites can be found on the immense footwall exposure along a southwest facing anticline limb.

There are footprints exposed here, but the majority are on the southwest-facing anticline limb (to the left)

Blocked off tunnels to the former underground mining operations are to the right.

The footwall only has a 40 degree slope, but is a pretty terrifying site to look for footprints. The debris field from the failing rock layers on the footwall are treacherous to walk upon. A single step can disturb piles of rock near the angle of repose causing small landslides. Even a minor shift of a block can cause a person to slip or trap a leg.

Some in situ tracks and trackways may be found like these ankylosaur trackways which are stained with the mineral limonite.


There are scores of natural casts to be found in the talus piles, almost all identifiable as ankylosaur manus or pes tracks.

The slope failures have exposed several in situ tracks and trackways too. Initially, only ankylosaur trackways were found, but in the summer of 2001 two large theropod trackways were found on a rippled substrate.
