1. Formation of Ayres Natural Bridge Marker
Inscription. Meandering La Prele Creek drainage cuts into alternating layers of sandstone and sandy limestone of the Permian / Pennsylvanian Casper formation.

La Prele Creek erodes both the upstream and downstream sides of the outcrop.

Undercutting by creek collapses the lower level of stone forming the bridge. The creek then follows the shortcut, flowing undern the bridge.


In memory of Lou B. Reed
