. The Owl Rock Member of the Chinle Formation, composed of cherty limestone and limestone conglomerate beds alternating with claystone, mudstone, and siltstone beds, forms the upper half of the mesa, and it overlays the Petrified Forest Member of the lower half. The Owl Rock Member is best exposed at its type locality near the base of Owl Rock. Here the member crops out and the resistant limestone beds form a series of jutting ledges that serve partly in protecting the underlying strata. The limestone beds are very resistant to erosion, forming thin ledges interrupting the slopes weathered from the dominant siltstone interbeds. The Owl Rock Member ranges in thickness from approximately 120 to 166 feet, and at Owl Rock the member is 166 feet thick.
