Bonny Benchmark is located west of I-15/Exit 128 (Osgood Area), about 9 miles north of Idaho Falls. This peak is located on private land, so please obtain permission from the landowner before undertaking this hike. An old 2-track road leads most of the way to the summit. USGS Shattuck Butte

Access
From Exit 128 (Osgood Area) on I-15 north of Idaho Falls, drive west then south on [signed] North 26th West Road for 1.9 miles to a signed junction with West 113th North Road. Turn right/west onto West 113th North Road and drive 5.9 miles to an unsigned junction with a dirt road that heads right/north directly at [obvious] Bonny Benchmark, which has two radio antennas on top. Park at this junction (4,970 feet) near some farm buildings and farm machinery. There are no signs, orange paint, or fences prohibiting entry but this is private land.

The Climb
Hike north up the 2-track road to where it bends sharply left/west. Leave the road here (or soon after) to scramble up through easy scrub in a north-northwest direction to reach the flat summit area. The hump to the left/south of the radio towers is the high point and has a benchmark near the summit boulders.
