How Geocaching Works
Use of geocaching.com services is subject to the terms and conditions in our disclaimer
From this site you can observe birds, butterflies, and other wildlife, as well as the unique vegetation known as a "shinnery."
This facility is part of the Balcones Canyonlands National Wildlife Refuge. It was established to protect the habitat of the endangered Black-Capped Vireo and Golden-Cheeked Warbler. To confirm your visit, e-mail me with the answer to this question: on the sign just outside the wooden structure, what bird is pictured on the nest?
