Mount Baker 2-Day Coleman-Deming Glacier Expedition¶

Two-day Coleman-Deming Glacier ascent of Washington's most glaciated volcano — crevasse navigation, Roman Wall steep snow, and the summit ice cap at 3,286m.

Overview¶

Mount Baker (3,286m) in Washington's North Cascades is a heavily glaciated stratovolcano receiving more annual snowfall than almost any other mountain in North America. The Coleman-Deming route is the standard ascent — a classic glacier climb starting from the Heliotrope Ridge trailhead (1,220m), crossing the Coleman and Deming Glaciers to the summit ice cap. The route involves crevasse navigation, roped travel, and moderate steep-snow sections on the Roman Wall near the summit. A wilderness permit is required. The mountain is excellent for those progressing toward larger glaciated peaks such as Rainier or Denali and offers a genuine Cascade glacier climbing experience.

Day 1: Heliotrope Ridge Trailhead to Coleman Glacier Camp¶

Hike from the Heliotrope Ridge trailhead through old-growth forest and across moraines to the Coleman Glacier edge. Rope up and cross the lower Coleman Glacier to a tent camp at 2,134m. The Roman Wall — the steep summit headwall — is clearly visible above. Afternoon crevasse rescue practice is common with guided parties.

Day 2: Glacier Camp to Summit and Return to Trailhead¶

2 AM departure across the upper Coleman Glacier and junction with the Deming Glacier. The Roman Wall is a 40-45 degree snow and ice headwall — the technical crux. The summit ice cap at 3,286m has fumarolic activity below the Sherman Crater. Return fully to the trailhead via the glaciers and forest.
