Description

Elephant Tusk is part of the Chisos Mountains where it is set in Big Bend National Park and the Chihuahuan Desert. The mountain is an igneous intrusion composed of rhyolite which formed 29 million years ago during the Oligocene period. [4] [5] Based on the Köppen climate classification, the mountain is located in a hot arid climate zone with hot summers and mild winters. [6] Any scant precipitation runoff from the peak's slopes drains to the Rio Grande which is 11 miles (18 km) to the south. Topographic relief is significant as the summit rises 1,950 feet (594 m) above surrounding terrain in one-half mile (0.8 km). The mountain's toponym was officially adopted on March 9, 1939, by the United States Board on Geographic Names after having been marked as "Indianola Peak" on various maps dating back to 1905. [3]
