Antelope Butte is a double-humped butte that is located in a remote area of the Snake River Plain, northwest of American Falls. It is easily reached on decent roads to within about a mile of the summit. USGS Sunset Lake

Access
From ID-39 about six miles west of Springfield and about 50 feet west of MM26, turn right/north onto [signed] 2600W/Butte Round Road and reset your odometer. 2600W is a wide, gravel county road that heads north and turns left/west to become [signed] 500S/Coffee Point Road. At 11.5 miles, reach a critical signed junction. This is Coffee Point on maps. From here, a smooth, wide gravel road heads left/west to Rock Lake (8 miles on the BLM sign) for the Split Top climb. Another road continues straight/northwest for the Antelope Butte climb.
Reset your odometer at the Coffee Point junction. Head straight/northwest on a road that leads to the Antelope Butte area. At 2.2 miles, go straight/northwest at an unsigned junction. The road is smooth, fast gravel to this point. At 7.0 miles, reach an unsigned “T” junction (Junction 5194 on maps). Go right/north here. At 9.0 miles, reach a signed “T” junction (Junction 5132 on maps). Turn right/north onto a 2-track road and drive 0.4 miles and park along the road [5,119 feet; 43°14’56”N, 113°06’58”W].

The Climb
From the 2-track road, bushwhack north-northwest across to the west side of a dry gully. From there, climb north up an easy slope of grass and scrub to skirt just below Point 5380 (the southeast summit hump) on its left/southwest side. Continue north-northwest to the cairned northwest summit, which is the high point of Antelope Butte.
