Peak 5578 is situated northwest of White Valley and west of Deep Creek at the south end of the Deep Creek Mountains. This area is a patchwork of public and private land so be careful. This route is entirely on BLM land. Peak 5578 is most easily accessed via a BLM road that begins about ½ mile north of Hess Road on Arbon Valley Road. USGS Holbrook
From the [signed] junction of ID-38 and Arbon Valley Road (a few miles east of Holbrook, ID), reset your odometer and drive northwest on [paved] Arbon Valley Road. At 5.4 miles, reach a [signed] junction with Hess Road/BLM-029. Turn left/southwest onto Hess Road and park along the road near an old, broken-down corral close to road junction (4,935 feet).
The Approach, Class 2
From Hess Road, bushwhack northwest then west across a field of tall sagebrush to intercept a 2-track BLM road (shown on the USGS topo map). Use a good, albeit narrow, horse trail to expedite the traverse across the field of sagebrush. The BLM road is in surprisingly good shape and, if accessible, should be drivable all the way to the base of the northeast ridge. Hike west then southwest along the BLM Road for about a mile to reach the base of the [obvious] northeast ridge of Peak 5578.
Northeast Ridge, Class 2
Leave the 2-track BLM road and weave your way through a jungle of tall sagebrush in a flattish field to reach the base of the well-defined ridge. Scramble up through normal sagebrush to reach the ridge crest. Follow the ridge southwest directly to the summit. The ridge terrain is easy sage and field grass. The summit had a torn-down cairn so I rebuilt it.
