Age. Presumed to be Rancholabrean and some of the fauna clearly is, but some may be Holocene.
General Description. A small, mostly vertical, opening into limestone. It has been mined, with a spoil pile near the entrance. Fossils were retrieved from the spoil and from thin fill left along the bottom of the vertical crevice. The site was discovered by UTEP botanist, Richard Worthington.
Discussion. The presence of the Common Muskrat is especially interesting since it indicates the presence of permanent water nearby. The only likely candidate is the Mimbres River, now a southward-draining ephemeral waterway running parallel to the Florida Mountains.
