Updrafts along cliffs create a perfect environment for soaring birds. They can be seen rising thousands of feet catching thermals out above the arid landscape. You can watch the them starting out low to the cliffs, circling and rising to find warm air then disappearing to become small dots high above. There is something inspiring about this simple natural behavior. It is one of the many remarkable things to be found along the borderlands of Texas.

The Devils River meanders through West Texas and finally reaches the Rio Grande at Lake Amistad. Devils River Canyon, which is partially flooded by waters behind Lake Amistad reservoir, is a spectacular sight. Vertical limestone cliffs rise a hundred meters or more above the river. The canyon can be explored by small watercraft for some distance upriver from the lake.
