Glacier National Park Ski Tour

The biggest issue here is the missing avalanche forecast. Glacier NP sits outside mapped forecast zones, so there's no bulletin to lean on. That means you're operating on field assessment only — which is workable for experienced parties, but you need to treat that like the serious constraint it is, not a technicality. Build in time on day one to do snowpack tests before committing to steeper terrain.

The weather pattern is the other key factor. A slow-moving storm system is loading the area through the weekend: chance of snow showers today and tonight, light snow likely Sunday (63% precip probability), and lingering snow chances into Monday. Highs are staying well below freezing — 24°F Sunday, 33°F Monday — so this is all dry snow loading, not a wet slide concern. Winds are light to moderate (6–14 mph out of the north and east), enough to cause some wind slab development on lee aspects, particularly west and southwest faces as the east wind component builds Sunday and Sunday night. Not howling, but worth probing before you drop into anything leeward.

SNOTEL data is a mess for this location — the nearest stations (Annie Springs at 6,021 ft, Long Lake at 840 ft, McNeil Canyon at 1,348 ft) are all at low elevations and showing falling trends, which likely reflects spring melt at those elevations, not what's happening at your tour elevations. The 37-inch snowpack depth reported for the area is reasonable for late April in GNP at mid-elevation. Don't extrapolate the low-station SNOTEL numbers to upper terrain. The stream gauges in the data are from central California and are irrelevant to this trip.

For timing and logistics: you've got 14+ hours of daylight, so no pressure there. Plan to move early and spend the first few hours of each day doing field assessment — extended column tests, pole probing on rollovers, watching for shooting cracks or whumpfing. Temperatures are staying cold enough that afternoon wet slide risk is essentially zero this trip. Your real unknowns are what the sustained storm cycle has been doing to the existing snowpack structure and whether new loading Sunday creates reactive storm slabs. Stay on slopes under 35 degrees until your field assessment gives you confidence, and avoid obvious wind pillows on SW-W aspects coming out of Sunday's ENE wind.
