Lithology description: There are two beds of tracks in limestones that contain abundant fine-grained subangular quartz and a few oolites. A third bed contianed a track found atop a siltstone. Bed is "quartzose, fine-grained, and very calcareous. It is light olive-gray unweathered, weathers to grayish green and pale yellowish brown, and is intensively bioturbated (massive)." | |
