Glacier National Park Ski Tour
Northern Rockies, MT
Elevation Profile
Current Conditions
Bottom Line
No avalanche forecast zone covers this location, so you're flying blind on slide risk — late May at Glacier means wet avalanche danger is real and you need to treat it accordingly. High of 55-57°F through the weekend will push the snowpack into wet, heavy, afternoon-slide territory. Start early, be off exposed aspects by noon.

Full Briefing
The biggest issue here isn't what we know — it's what we don't. There's no avalanche forecast zone covering this location, which means no professional assessment of the snowpack structure, recent activity, or problem layers. Late May in Glacier at elevation is not the time to assume that means no risk. With daytime highs hitting 55°F today and climbing to 57°F by Sunday, the snowpack is actively melting during the day. Wet loose avalanches on steep sun-exposed terrain are a real threat every afternoon. Treat any slope over 30 degrees on south, east, and west aspects like Considerable danger after 11 AM — because that's the honest analog for this temperature regime even without a formal bulletin.
The SNOTEL picture is messy. Long Lake at 840 ft shows 61 inches depth and 26.4 inches SWE on a falling trend — that's a low-elevation station actively melting out. Annie Springs at 6,021 ft shows zero depth, meaning the lower and mid-elevation snowpack has largely consolidated or melted. Your rideable snow is going to be patchy below about 7,000 ft and concentrated on north-facing aspects. Expect variable, heavy, wet snow on sun-exposed terrain by midday, with firmer corn on north aspects in the morning window.
Weather looks workable Friday and Saturday — mostly sunny with light winds under 16 mph WSW, minimal precip chance. Sunday is the day to watch: winds build to 13-23 mph SW, which at ridge elevation will be loading north and east aspects all day. If there's any fresh snow from Friday night's shower chance (27% precip, could be wet snow above 6,500 ft), Sunday's wind could build a fresh wind slab on lee aspects. Without avalanche data, you can't know what's underneath it.
Logistics: with 15.5 hours of daylight and sunrise at 5:46 AM, you have a huge morning window — use it. Boots on snow by 6:30 AM to catch frozen surfaces before solar heating kicks in. Plan to be off exposed terrain by noon each day. Friday and Saturday are your best objectives. Sunday, stick to mellow angles or north-facing trees unless you're comfortable managing unknown wind slab risk on top of a wet, unsupported snowpack. Stream crossings are normal at all five gauges — no issues there.

About This Route
Glacier National Park transforms into a backcountry skiing paradise in winter, with Going-to-the-Sun Road providing a groomed approach corridor to spectacular alpine terrain. The route follows the road to Logan Pass before branching into the surrounding peaks. The area around Logan Pass offers rolling alpine terrain with options for all skill levels. Moderate tours explore the Oberlin Meadows area, while advanced skiers can access steeper terrain on the flanks of Mt. Oberlin and Clements Mountain. The snowpack is generally deep and the terrain is dramatic. Winter access requires skiing or snowshoeing the closed highway, which adds significant distance but rewards with utter solitude. Check with the Flathead Avalanche Center for current conditions. The park requires no additional permits for day touring.
