Climbing the Walrus Glacier

From Lake Wenatchee, drive White River Road (FR 6400) to its end at the White River trailhead; the Forest Service reports washouts and sinkholes, so check conditions first. Walk the flat White River Trail 4 miles, then climb the Boulder Creek Trail to camps below Boulder Pass, with a ford near 4,000 feet. Traverse east to the Walrus Glacier, rope up through crevasses to the 8,000-foot col, and finish on Class 2 to 3 rock. Bugs are fierce in July. A Northwest Forest Pass is required to park, and you fill out the free wilderness permit at the trailhead.
