Bridger Jack Butte is a sandstone butte located in Bears Ears National Monument, in San Juan County, Utah, United States. Set at the northern tip of Bridger Jack Mesa and above the confluence of Indian and Lavender Creeks, the summit rises to an elevation of Шаблон:Convert, and towers over Шаблон:Convert above the surrounding terrain and floor of Lavender Canyon to its west.[1] This landmark is situated four miles southeast of the Sixshooter Peaks, and is visible from State Route 211 between Newspaper Rock and the Needles District of Canyonlands National Park. "Bridger Jack" was a Paiute medicine man.[2]

Geology

Bridger Jack Butte is composed of hard, fine-grained Wingate Sandstone, the petrified remains of wind-borne sand dunes deposited approximately 200 million years ago in the Late Triassic. This Wingate Sandstone forms steep cliffs as it overlays softer layers of the Chinle Formation.[3] The next layer below this is the Moenkopi Formation.[4] Precipitation runoff drains into nearby Indian Creek, which is part of the Colorado River drainage basin.

Climbing

Bridger Jack Butte is set in the popular Indian Creek climbing area. The first ascent of Bridger Jack Butte was made June 12, 1983, by Ed Webster, Leonard Coyne, and Ellen Figi, via the Wild Flower route.[5] The "Bridger Jacks" are towers on the connecting ridge between the mesa and the butte. They have names such as "King of Pain", "Hummingbird Spire", "Sunflower Tower", "Easter Island", and "Thumbelina".[6]
