Flat Top Butte is located next to ID-46 and the junction for the dirt road that leads to the Gooding City of Rocks. The peak is one of the most correctly named structures you can find. USGS McHan Reservoir
A dirt road accessible from ID-46 circles the butte on three sides. Leave the highway on its northeast side. Follow the dirt road to a barrow pit on its west side.
West Slopes, Class 2
Climb the peak via its western slopes. There is a two track that scars the western slopes. You can climb it or the slopes just to the north. Aim for a point north of the distinctive rocky point. Move onto the north slope just before the top and then go straight up to the summit platform. From this point walk due east to the highest point where there is a cairn and a wooden cross.
Northeast Face, Class 3 by Livingston Douglas
Date of Climb: October 13, 2019
From its junction with US-20, drive south on ID-46 for 13.7 miles to the signed turnoff for “City of Rocks Road.” Turn R/W onto this road and park in a large pullout at the base of the road (5,275 feet). There is a large BLM posterboard/sign here for “Bennett Hills.”
From the parking pullout, climb SW directly up the steep face through reasonably easy sagebrush (short and gapped), aiming for a rocky outcrop at the L/E end of the butte. Higher up, as you approach the summit plateau, the terrain gets rough and is a combination of large boulders and brush. To gain the summit plateau, you must climb surmount the summit cliff band (Class 3 unless you find a Class 2 chute to the R/W).
The summit has a cross made of triangulation posts at its E edge (not quite the high point). The actual high point is one of two points. The first one is only 20 feet or so NW of the cross where there is a large boulder. I built a cairn atop this boulder. It is also possible that the high point is about 100 feet W of the cross where there is a summit cairn. The summit plateau is a bit clunky due to a combination of scrub and ground talus/boulders. This climb was much more fun than the scramble up Windy Benchmark, which I had done immediately prior to driving to City of Rocks Road and completing this climb.
