Elaterite Butte is a Шаблон:Convert elevation summit located in The Maze District of Canyonlands National Park, in Wayne County, Utah.[1] Elaterite Butte is situated Шаблон:Convert southwest of Ekker Butte, and the Maze Overlook is situated Шаблон:Convert to the northeast. Elaterite Butte is composed of hard, fine-grained Wingate Sandstone, which is the remains of wind-borne sand dunes deposited approximately 200 million years ago in the Late Triassic. This Wingate sandstone overlays a 432-foot thick layer of the softer Chinle Formation.[2] The top of this geological formation rises over 1,400 feet above Elaterite Basin. The butte and basin are named for elaterite, which is a dark brown, tar-like, elastic mineral resin that seeps from parts of the nearby White Rim Sandstone.[3] Access to the remote butte is via a four-wheel drive road in Elaterite Basin. Precipitation runoff from Elaterite Butte drains into the nearby Green River, which in turn is within the Colorado River drainage basin.
