Salt Basin and Guadalupe Peak
From a playa in the Salt Basin one can view a spectacular cross-section of the Guadalupe Mountains illustrating the reef/fore-reef relationships during the Permian geological period.
Guadalupe Peak, the highest peak in the mountains, is nearly a mile higher in elevation than the valley floor.
Salt Basin is the beginning of the Basin and Range Province in Texas. Quaternary faulting is prominent on its western flank along Sierra Diablo.
This map shows how the Basin and Range Province trends northwest/southeast through the western part of Texas.
