The Black Pine Mountains are located just north of the Utah border and west of I-84. Geographically, the range is the most distinctly defined mountain range in Idaho. It is surrounded by wide, flat valleys, and rises steeply on all sides. Geologically, the range is a textbook example of a Great Basin mountain range. The fault block, which forms the entire range, rises to 9,395 feet on Black Peak and is surrounded on all sides by broad alluvial fans.
