Mount Baker

The season varies dramatically by activity. Glacier climbing and ski mountaineering: April through June (the spring snowpack is stable; crevasse hazard is reduced by winter bridging; the corn snow is superb for descent; July and August bring crevasse opening and increased rockfall). Summer hiking: mid-July through early October (the Artist Point road — the last 4 miles of WA-542 to Artist Point — is typically snow-free by mid-July; the wildflower peak is late July through mid-August; the Chain Lakes Loop is spectacular in late July). Downhill skiing at Mount Baker Ski Area: November through April (the world-record snowfall creates the earliest opening and latest closing of any major Washington ski area; the ski area sometimes operates into May). The Artist Point road typically opens in late July (later than any other mountain road in Washington State due to the extreme snowpack); check USFS for current road status. July through September for the hiking and the wildflowers, April through June for the glacier and ski objectives.

Mount Baker (Komo Kulshan) was sacred to the Lummi, Nooksack, and other Coast Salish peoples who inhabited the foothills around its base for thousands of years; the mountain was a spiritual presence of overwhelming scale in the landscape. Euro-American discovery is credited to the Spanish explorer José María Narváez (who sighted the mountain from the Strait of Georgia in 1791) and the British explorer George Vancouver (who named it for his sailing master Joseph Baker in 1792, while exploring the Strait of Juan de Fuca; Baker sighted the peak and it was named for him). The first Euro-American ascent was made by Edmund Coleman in 1868 via the Easton Glacier route — a relatively early ascent in the history of American mountaineering. The volcano’s 1975-1976 episode of increased fumarolic activity (the Sherman Crater produced a dramatic increase in sulfurous gas emissions, causing concern about a potential eruption) led to evacuation planning and scientific monitoring that continues to the present. Mount Baker Ski Area opened in 1927, making it one of the oldest ski areas in the American West.

Mount Baker is a Quaternary stratovolcano — a composite volcanic cone built from alternating layers of lava flows, pyroclastic material, and lahar deposits erupted over approximately the past 1 million years. The volcano sits above the Cascadia Subduction Zone, where the Juan de Fuca oceanic plate subducts beneath the North American plate; the partial melting of the subducting plate generates the andesitic magma that feeds the Cascade arc volcanoes. Mount Baker’s most recent eruptive period was approximately 6,600 years ago (a major eruptive episode that produced widespread pyroclastic flows and lahars); the 1975-1976 increase in fumarolic activity in the Sherman Crater (the active volcanic vent on the south side of the summit) was the most significant recent volcanic unrest. The Sherman Crater fumaroles (sulfurous gas vents) are responsible for the distinctive sulfurous odor near the summit and for the acid-altered yellow-orange rock visible in the crater walls. The mountain is capped by the largest concentration of glaciers by area of any Cascade peak outside of Mount Rainier — 10 named glaciers covering approximately 10 square miles.

Mount Baker’s subalpine and alpine habitats support the characteristic wildlife of the North Cascades high country. Mountain goats are abundant on the rocky terrain of the upper mountain and the adjacent Table Mountain and Ptarmigan Ridge areas — they are frequently visible from the Artist Point and Chain Lakes hiking areas, sometimes at very close range. White-tailed ptarmigan inhabit the alpine tundra. Hoary marmots are the dominant marmot of Mount Baker’s subalpine zone (replacing the yellow-bellied marmot of more southerly mountains). American pika inhabit the boulder fields on the approach to the mountain. Wolverines (the largest terrestrial member of the weasel family; one of the rarest and most wilderness-dependent mammals in Washington State) are present in the Mount Baker wilderness; the deep, persistent snowpack is critical wolverine denning habitat, and Mount Baker’s extraordinary snowpack is identified as significant wolverine habitat in Washington State wolverine conservation planning.

Mount Baker’s ecological character is dominated by the extreme snowpack — the world-record 1,140-inch winter (95 feet of snow in a single season) represents the extreme end of a consistently deep snowpack that averages 650+ inches per year in the summit area. This extraordinary snow depth creates an alpine ecosystem dominated by the snow dynamics — the subalpine meadows are snow-covered for 9-10 months per year (a 6-8 week growing season); plants must complete their entire annual growth cycle — germination, flowering, pollination, seed set, and seed dispersal — in this compressed window. The wildflower display in the Artist Point and Ptarmigan Ridge meadows is the result of this compressed cycle — dozens of wildflower species bloom simultaneously in a spectacular burst in late July and early August. The glaciers of Mount Baker are retreating due to climate change, but the mountain’s extraordinary snowfall has buffered the rate of glacier retreat compared to other Cascade peaks.

Mount Baker holds a unique place in the outdoor culture of the Pacific Northwest — the world-record snowfall mountain, the most active volcano in the North Cascades, the finest backcountry skiing objective in Washington State, and a volcanic silhouette that dominates the skyline of northwestern Washington from Seattle to Vancouver, BC, giving the region one of its most distinctive and most beloved landscape icons. Mount Baker is revered by the Lummi and Nooksack peoples; its Lummi name — Komo Kulshan, “the great white watcher” — captures the mountain’s commanding presence in the regional landscape. For the skiing and mountaineering community of the Pacific Northwest, Mount Baker is a pilgrimage destination of the first order.

Mount Baker is accessed from Bellingham, Washington, via WA-542 (the Mount Baker Highway) east approximately 60 miles to the road end at Artist Point (summer) or the ski-area base (winter). Bellingham (60 miles west) has full resort services. The Mount Baker Ski Area is approximately 56 miles east of Bellingham via WA-542. Artist Point (the summer road terminus at 5,140 feet) is approximately 4 miles east of the ski area; the Artist Point road is typically open from late July through October (check USFS for current road status — it is often the last road in Washington to open due to snow). Glacier climbing trailheads (Schreibers Meadow for the Easton Glacier route; the Heliotrope Ridge trailhead for the Coleman Glacier route) are accessible from WA-542 via forest roads (check USFS for road conditions). An USFS recreation pass (America the Beautiful or Northwest Forest Pass) is required at most trailheads.

The Mount Baker-Snoqualmie National Forest manages the Mount Baker area; the upper mountain and glaciers are within the Mount Baker Wilderness (Wilderness Act designation). The most critical conservation issues are maintaining the quality of the wilderness experience on the glaciated mountain (the heavily used Easton and Coleman Glacier routes generate significant human-waste impact above the snowline; use a WAG bag for all human waste above the snowline; it is both ethically required and increasingly legally mandated) and protecting wolverine habitat (the deep, persistent snowpack of the Mount Baker area is identified as critical wolverine denning habitat; snowmobile use in designated motorized areas should not penetrate the wilderness boundary). The Artist Point meadows are fragile subalpine tundra; stay on designated trails at all times. Respect all climbing-area closures for glacier-hazard assessment.

Glacier travel on Mount Baker requires technical mountaineering skills — crampons, ice axe, rope, harness, and crevasse-rescue training are all required; the glaciers have open crevasses by June and July that can be concealed by snow bridges; a rope team of at least 3 persons trained in crevasse rescue is the minimum safe party for any glacier route. The volcanic hazard (Mount Baker is an active volcano; the Sherman Crater fumaroles are the surface expression of the volcanic system) is low but non-zero; check the USGS Cascades Volcano Observatory (CVO) for current volcanic-activity status before any summit attempt. Altitude sickness can affect visitors on the summit (10,781 feet); acclimatize in Bellingham or Glacier for at least one night before attempting the summit. The Artist Point area is subject to sudden summer storms (high winds, lightning, and snow can occur at any time of year); always carry full mountain gear. Avalanche hazard is extreme during the winter and spring on all routes; carry avalanche beacon, probe, and shovel for any winter/spring backcountry travel.

Northwest Forest Pass or America the Beautiful Pass required at most trailheads. Wilderness permit may be required for overnight glacier travel (check USFS for current permit requirements). Glacier climbing: no permit required (self-register at the trailhead). WAG bag required for human waste on the glacier above the snowline (increasingly enforced; carry a WAG bag for any summit attempt). No camping within the Artist Point area without a designated backcountry permit (check USFS for current rules). Campfires prohibited in the Mount Baker Wilderness (use a stove). Check USFS for current fire restrictions. Artist Point road: closed by snow from approximately November through late July (check USFS for current status before any spring or early-summer visit). Overnight parking at ski-area lot during off-season: check USFS for current rules.

Bellingham, Washington (60 miles west via WA-542 — a vibrant college town with Western Washington University, a lively waterfront, and excellent services as the primary gateway city for Mount Baker), the Nooksack River (flowing west from the Mount Baker glaciers — a wild river with excellent summer steelhead and salmon fishing and Class IV-V kayaking in the lower Nooksack Canyon), North Cascades National Park (accessible from WA-20, 30 miles south of the WA-542 corridor — Diablo Lake and the North Cascades Highway), the San Juan Islands (accessible from Anacortes — 40 miles southwest of Bellingham by road — via Washington State Ferry), and Vancouver, BC (50 miles north of Bellingham via I-5 and the Canadian border) define the regional context. Mount Baker anchors the northwestern corner of the Washington Cascades outdoor experience.

For the finest single-day experience of Mount Baker without technical mountaineering gear, drive WA-542 to Artist Point (open approximately late July through October; check USFS for current road status) and hike the Chain Lakes Loop (6.9 miles; 1,300 feet of gain; approximately 3-4 hours) around Table Mountain through the Chain Lakes to a full circumnavigation of the Table Mountain plateau with continuous, close-range views of Mount Baker’s glaciated west and north faces, Mount Shuksan (one of the most photographed peaks in North America), and the extraordinary subalpine wildflower meadows. The wildflower peak is typically the last week of July through the first week of August; the combination of lupine fields, Indian paintbrush, avalanche lily, and mountain daisy against the glacier-clad volcano is extraordinary. For ski mountaineers, the Mount Baker spring-ski season (March through May on the lower Coleman and Easton Glacier routes) offers the finest volcano-ski experience in Washington; hire a Bellingham-based guide service for your first trip.
