Take Exit 62, Kachess Lake, off of I-90. Cross over freeway and follow Forest Road 49 to Kachess Lake Campground. Turn left and drive to fork (200 yards). Take the right fork, marked #4930 and "To trail #1313". Drive and cross Box Canyon Creek bridge (signed). Take the first left (about 4 miles from the campground, unsigned). Drive to the road's end at parking lot, 2800 ft.
APPROACH & ASCENT
Start at Rachel Lake trailhead. Reach the scramble route start at 3,300 ft in 45 minutes. You'll pass through a brushy area from which you can see the summit and then head into the forest. Once in the forest there is an obvious boot path heading northeast up the slope. Follow the path up towards the summit. The path gets fairly steep and after about 500 feet of elevation gain, the trail enters a small clearing. Stay right and be careful not to lose the trail towards the summit.
As you climb towards the summit there is a rock band at about 5,300 feet. Go right around the band following the trail to a large sloping meadow. Climb up and then slightly right, lining up roughly with the right (south) side of the summit block. This leads into a very loose talus/scree field (watch for falling rocks). Follow thready boot path up to the south side of Hibox summit block. Do not ascend the obvious gully on the southwest side of the summit block; rather keep right as you climb. As you approach the summit block, there is a short notch that runs up to the rock above. There is some exposure, but the rock is good, and the scramble to the summit is easy from this point.
