Panther Peak is a 6,418-foot summit in the Chisos Mountains of Big Bend National Park in far West Texas, rising from the Chihuahuan Desert with a steep, prominent profile. Formed of rhyolite during the Oligocene, it reflects the ancient volcanic history of the range. Although moderate in absolute elevation, the summit climbs about 2,000 feet above nearby terrain within a mile, making it stand out in the landscape. Its lower slopes support juniper, oak, and piñon in a hot arid climate, and runoff drains northeast toward Tornillo Creek. The name was officially adopted in 1939 and comes from nearby Panther Spring.
