Coleman-Deming Glacier

Length:3 days
Price:1 climber $1,350
2+ $825 per climber
Dates:Custom dates/private guides are available in July and August
Location:Mount Baker

The Coleman-Deming Glacier route lies the north side of the peak and is similar in difficulty to the Easton Glacier. The C-D route is the most popular climb on the peak and offers the climber the chance to experience some steeper snowfields and glacier climbing techniques.

Alpine skills

To start of our trip we will hike in on the north side of Mount Baker via the Heliotrope Ridge trail near the town of Glacier.  We will find a suitable place to camp between six and seven thousand feet and instruct or review fundamental skills. Our second day allows time for instruction that will be applicable on our summit day.  The course day will include instruction in glacier climbing as well as introducing crevasse rescue skills.

Summit day

The third day we will be up for an alpine start around midnight or a bit later depending on conditions.  Our climb will take us up the Coleman Glacier on the North side of Mount Baker before wrapping around to the west and the upper portion of the Deming Glacier.  We will encounter some steeper terrain before reaching the summit plateau and the actual summit.  To descend, we will retrace our climbing route as we head back to camp. Once at camp we will pack up and start our hike out heading back to the Heliotrope trail head.

Mount Baker

The Coleman-Deming route on Mount Baker is a beautiful glacier route, that weaves around huge crevasses and through a steep headwall, before reaching the summit plateau. This is a great introduction to glacier travel, and an excellent location to spend extra time practicing crevasse rescue. Seracs at the toe of the glacier is a great location to work on ice climbing and advanced glacier travel.

"I am very happy with my TMG experience. The guides were professional, personable, and extremely concerned about safety. . . I absolutely give highest marks to these guys. If you don't have much Alpine experience, or just want the security of seasoned veterans guiding you up this mountain, then I strongly recommend you sign up with them. Thanks, guys, for a great experience!!"

"What a fantastic experience gaining the summit of a mountain we've gazed on from Portland for 25 years! . . . We learned a great deal, had a ton of fun, felt in very capable hands, and had the reward of summiting on a beautiful clear day. The value of being with a professional, certified, guide and guiding organization was evident throughout. Kudos to the TMG team who were responsive, supportive, and fun to work with every step of the way."

"We booked 2-day overnight program on Mt. Hood with Timberline Mountain Guides. Our guides were great, . . super friendly and reputable. The program did not go as planned due to inclement weather but we still had fun and good experience. The guides were definitely flexible and provided guidance during the trip. I would recommend going with them if it's your first climbing trip on Mt. Hood for sure."
