Take Highway 542 east from Bellingham, turn right onto Glacier Creek Road (FR 39) at Glacier, WA. Drive 8 miles to trailhead on the left. Northwest Forest Pass required.

The most popular route on Mount Baker, the Coleman-Deming combines the Coleman and Deming glaciers in a classic northwest glacier climb. The route offers sustained glacier travel, impressive crevasse scenery, and a straightforward summit push on the Roman Wall headwall.

Route Description

The original and most-climbed standard route on Mount Baker (first summited via this line in 1868), approaching from the north side via the Coleman Glacier before finishing on the Deming Glacier and Roman Headwall.

Approach

From the Heliotrope Ridge Trailhead, hike the Heliotrope Ridge Trail through forest to treeline, then follow a climber's path up the Hogsback moraine to the toe of the Coleman Glacier (~6,000 ft), where most parties rope up.

Descent
