Black Rocks is a rocky mess located on the west side of ID-51 about 11 miles south of Bruneau. Finding the high point amongst the endless rocky outcrops is a bit of a challenge. Surprisingly, the summit is a grassy hump rather than a black rocky outcrop. USGS Hole in Rock

The Climb
From the improvised parking spot on the spur road, head west downhill. Bend right-ish/northwest and go up and down several hills to reach an area of black rocks. Keep heading northwest or west to finally reach the high point in an area that has several black rock outcrops. But the high point is a gentle, grassy hump with no rocks. That was a real surprise.
