Chihuahuan Desert Research Institute gladly hosts Ranger Rick's Geocache Trails program, part of National Wildlife Federation's-Be Out There-movement. CDRI is open Monday to Saturday from 9 AM to 5 PM. This is the first of eight caches. For more information go to the front desk of the visitor center to receive your Ranger Rick passport, stamp your first find, get the coordinance of the other seven caches, and pay your admission fee. Enjoy, have fun and don't forget to look up and see the sights, sounds, and smells of the Chihuahuan Desert.
