Mt. Baker Climb – Coleman-Deming Route

Climb the Coleman-Deming Route on Mt. Baker with Pacific Alpine Guides


Climb the Coleman-Deming Route on Mt. Baker with Pacific Alpine Guides

Mt. Baker’s Coleman-Deming route is one of the two standard routes on the mountain, offering interesting, moderate climbing on the third highest peak in Washington State and the second most glaciated peak in the Lower 48. This is an excellent route for developing experience on crevassed glaciers.

On a clear day, the Coleman-Deming route offers spectacular views of the surrounding North Cascades, the San Juan islands to the west, and even Mt Rainier over 100 miles to the south.

This program is 3-days in length. Day 1 we approach our high camp via the Heliotrope Ridge trail. Days 2 is focused on skills training and review in preparation for the summit ascent of Mt. Baker the following day. Day 3 is summit day, and the descent back to the parking lot.



We meet at 8am at the Glacier Public Service center in Glacier, WA for introductions and a gear check. After securing our permits we drive up to the Heliotrope Ridge Trailhead where our approach begins.

The approach takes us through old growth forest, sub-alpine transitional zones, and up onto moraines where we’ll place our camp below a lobe of the Coleman Glacier around 6,000’. We’ll be carrying 40-50 lb packs and climbing efficiency will be a theme of skills taught along the way.

We’ll construct a solid mountain camp, eat dinner, and relax for the evening. This is usually a 5-6 hour day.


The focus of this day will be learning and reviewing foundational mountaineering skills. This area is a prime venue – right out of our camp we have access to glaciers, allowing us ample opportunity to practice snow climbing techniques, ice axe arrest, cramponing, and roped travel.

In the afternoon we discuss the climb ahead and begin our preparations for the following day. In order to maximize our rest for the following day, we eat dinner on the early side and head for bed well before dark.


With a pre-dawn alpine start we begin our summit day. From our camp the route climbs steadily onto the Coleman Glacier, where the angle eases slightly and becomes more consistent. We climb towards a saddle between the upper mountain and Colfax Peak, a sub-peak of Mt Baker.

Our goal is find a steady rhythm that allows us to climb with maximum efficiency. We move for 1-2 hours at a time, stopping for 10-15 minute breaks between stretches.

Once above the saddle we encounter the steepest section of the route, the Roman Wall. Here the angle steepens to a sustained 35°+ for close to 1000’. Above the Roman Wall it’s a short walk across the summit plateau to the actual summit.

Depending on weather conditions we’ll spend 20-30 minutes on top, ample time to snap a few summit photos, have a snack, and take in the view.

It’s about a 3 hour descent to camp, and once there we take a short break and pack up our overnight gear. It’s another 3 hours or so back to the trailhead from here.

On the drive out we stop for a celebratory lunch where we wrap up our program.

Lunch Food: In the mountains, “lunch starts after breakfast and ends before dinner”. In other words, on a given day we generally won’t stop for a formal lunch break, and instead we’ll snack all day long. This is vital to maintaining high energy levels in this environment.

Be sure to bring foods that you like and emphasize variety. Energy bars and gels are great but in limited amounts – real food works just as well and tastes better.

Breakfasts & Dinners: Bring meals that can be cooked with just boiling water. Examples include freeze-dried pouches (Mountain House, Backpackers Pantry), ramen noodles, instant oatmeal, etc. The stoves we’ll use are very efficient for heating water but terrible for actually cooking anything.
