Hiking on the Coleman Glacier
The Coleman Deming is the standard route up Mount Baker, the Easton Glacier is the second standard route. While this is technically a walk up, it does require glacier travel and potential crevasse navigation depending on the time of year. This is a great beginner route for getting into glacier travel and for practice training for Mount Rainier. Even for the experienced mountaineer one enjoys a fun snow walk up a great Cascade Volcano. Along the way one enjoys great views of the towering Black Buttes which are crumbly towers with hanging glaciers. Climbers often use this as a descent route from the North Ridge, the Coleman Headwall, or the Pencil Thin Roman Mustache. You gain slightly over 7,000 feet of elevation with a distance of about  11 miles round trip. Commonly the Coleman Deming is done in two days but can be done in a single day if you get a very early start.

Getting There

View Google Maps Directions here. [121 Miles | 2 Hours & 35 Minutes]

From Seattle: Take I-5 for about 60 miles until you get to Mount Vernon, take a right at exit 230 onto Highway 20. After about .2 miles be sure to take a left onto S Burlington Blvd (this goes North). After .4 miles take a right back onto highway 20 (at this part of town it is known as Avon Ave). In 5.1 miles take a left onto Highway 9 heading North. In 22.2 miles take a right at a fork in the road and take a right onto highway 542 (Mount Baker Highway). In 8.3 miles turn right (staying on Highway 542) in the city of Kendall. 11.5 miles further down the road is the city of Glacier where you take a right onto Glacier Creek Road (NF Road 39). Follow this service road for 7.8 miles which the Heliotrope trailhead will be on your left. The road itself keeps on going which you ought not to proceed beyond the trailhead.

The road is usually snow covered in early season making it a longer approach (usually around 3-5 miles). Many decide on bringing ski's to make traveling faster.

Route Description

The trip starts out as a hike along the Heliotrope Ridge trail. After passing Kulshan Creek the trail curves left and wraps around a small ridge. After the second waterfall you arrive at a fork in the trail. The left path goes to Glacier Overlook, the right path is a climbers trail that takes you to the Coleman Glacier. After the fork the route breaks out of the trees where you start to see views of Baker and the Coleman seracs.

The main trail follows a hogsback moraine pathway and has at least one other variation if you miss this path. Roughly around 6,000 feet you encounter the beginning of the glacier. Through out much of the year it's hard to tell exactly where the glacier starts. Rope up as soon as the snow slope steepens.

At the edge of the glacier aim slightly east of point 7242 (Heliotrope Ridge). From Heliotrope Ridge head almost directly east for a while and eventually curve southward depending on how crevasses effect the route. Eventually you arrive at the saddle between the summit and Colfax Peak. Head left (east, lightly north) up the ridge that takes you toward the Roman Wall.

The ridge fades out which the route now goes onto the upper Deming Glacier. After heading up the last part of the glacier you arrive on the summit plateau. There is enough flat space to put up a football stadium. Walk across the plateau to it's northeast edge. The summit itself is a small nub of loose rocks, although can be snow covered depending on the time of year. On the summit you are rewarded with views of the Twin Sisters, Picket Range, Mount Shuksan, Puget Sound, and other various peaks in the area.

Where Are Our Footprints?
Don't Get Lost
There are no permits required for this climb, although you can fill out a trail register at the trailhead or ranger station.

The Glacier Public Service Center can be reached at 360-599-2714 and are opened year round. During the winter months they are opened Saturday to Sunday at 9:00 a.m. to 3:00 p.m. They are closed on federal holidays. From mid June to mid October they are open daily from 8:00 a.m. to 4:30 p.m.

Water Sources:
There are a few creeks along the Heliotrope trail. You may get lucky and find some running off the edge of the Coleman Glacier. Finally there is the glacier itself to melt snow.

Crevasses to Navigate
1) Glacier Travel - This route to the summit of Mount Baker involves crossing two glaciers. Many climbers and skiers tackle this route earlier in the season relying on the idea that with enough snow, crevasses will be filled in or covered up. This brings to mind the saying "There are old mountaineers and there are bold mountaineers, but there are not a lot of old-bold mountaineers." Don't be reckless. Bring the necessary gear to perform a crevasse rescue if a fall occurs. A buddy of mine has seen a crevasse fall on Baker as early as April.

2) Avalanche - In early season (before May) be aware of current snow conditions. There is a lot of places that has potential for slab avalanches.

3) Weather - Mount Baker being one of the Cascade volcanoes that reaches above 10,000 feet has unpredictable weather. Be prepared for all conditions. I have personally got caught in a snow white out near the summit during July. Others have too. A buddy of mine had to make a snow cave.

4) Serac Danger - Be aware during earlier season or times of high snow melt that seracs do break off from the Black Buttes onto the Coleman Glacier.

5) Rock Fall - Rocks do fall from the Black Butte from time to time which is something to be mindful of. During late August though October it is possible for the snow to melt off the ridge below the Roman Wall. When this happens the ridge becomes a scramble with loose volcanic rock.

Coleman Camp during Sunset
The Coleman camp is the most common place to camp along this route. It's located near a gap on heliotrope ridge near point 7242 on the east side. A good alternative is on top of Heliotrope Ridge itself where it is dry but is a few hundred feet extra of elevation gain. One could also camp right below the camp area as well as below the glacier. Theoretically you could camp at the trailhead or a ways up the trail where the old cabin used to be. If your feeling hardy you could also camp near the summit where it is very flat, but can be quite windy. It's been done, but is rare. Anywhere else on the glaciers I wouldn't recommend due to slopes and ice fall.

When to Climb

This route is often climbed between the month of April through August. The year snow pack plays a role in what month is best for climbing. The best time to climb this route is usually mid July when weather improves and avalanche danger is low. In August more crevasses form making navigation a bit trickier, but better chances of perfect weather. During the early season months the weather is usually bad, but if your lucky you may find a perfect day with low avalanche danger.

Children refers to the set of objects that logically fall under a given object. For example, the Aconcagua mountain page is a child of the 'Aconcagua Group' and the 'Seven Summits.' The Aconcagua mountain itself has many routes, photos, and trip reports as children.



Parents refers to a larger category under which an object falls. For example, theAconcagua mountain page has the 'Aconcagua Group' and the 'Seven Summits' asparents and is a parent itself to many routes, photos, and Trip Reports.
