The White Knob Mountains dominate the northern landscape of this Idaho interior, where the high desert floor of the Antelope Valley meets steep canyon walls. In the early 1990s, this area remained largely defined by the Lost River and its seasonal tributaries, such as Antelope Creek and Hooley Creek. The small settlement of Grouse and the Antelope Cem serve as the primary markers of community life in this remote stretch of Custer and Butte Counties. A network of unpaved trails and 4WD tracks, including Antelope Road, threads through the terrain, connecting isolated watering spots like Richardson Spring and Waddoups Spring. The presence of the Antelope Valley Airport near Dry Fork Creek highlights the logistical necessity of air travel in navigating these expansive Idaho ranges.
