T L Gap serves as a prominent landmark in this section of Teton County, where the topography transitions between the high elevation of Bole Bench and the carved drainages of the Teton River valley. The landscape is defined by a series of deep coulees including Antelope Coulee, Coyote Coulee, and Government Coulee, which illustrate the complex drainage patterns feeding into the river system.
