The Sierra Club also praised the designation, stating that the area was " a fitting addition to our protected public lands " because it is " one of the best examples of the spectacular basins framed by Nevada s breathtaking mountain ranges, a resting place for historic artifacts critical to understanding our nation's Native American cultural history, and home to unique plants and animals, some found only in Nevada and this region .
