Avalanche Crest #4

Avalanche Crest is a popular Rogers Pass ski tour on the southwest flank of Avalanche Mountain in Glacier National Park. The line follows the summer Avalanche Crest trail from the Illecillewaet parking area, then breaks onto the broad crest before dropping a sustained fall-line face back toward the Trans-Canada Highway. This #4 option is one of several parallel gullies and faces along the ridge, all feeding back toward the same lower fan near the road.

Terrain is a mix of open, west- to southwest-facing alpine and subalpine slopes with sparse trees, rolling convexities and multiple gullies. The slope is broad enough that you can easily drift into steeper, more exposed features or cliff bands, especially in flat light or storm snow. With a deep midwinter base, small pillow and cliff lines fill in and become skiable, but they are still serious terrain if you do not know the exits.

From the Illecillewaet lot, skin the old rail grade to the signed Avalanche Crest summer trail, then follow the well-used uptrack through forest to treeline and onto the ridge. The usual drop-in for this line is from the crest above the main southwest face, picking a gully or fall-line lane that keeps you away from obvious rock bands and overhead cornices. On the exit, trend skier’s right toward the highway, but stay alert for terrain traps, creek cuts and snowplow debris near the road berm.

This zone sits inside Glacier National Park’s Winter Permit System and portions of Avalanche Crest are within Winter Restricted Areas; you must check the daily WRA status and carry the required permit before leaving the lot. West-facing solar input rapidly changes the upper snowpack during clear periods, creating melt-freeze crusts, loose wet and storm slabs on buried crusts. The face also has large, unsupported rolls with significant overhead hazard, so stability needs to be solid before you commit to the main fall line.
