Eagle Peak South Couloir

Eagle Peak’s south side drops into a long, committing couloir above Rogers Pass in Glacier National Park. Most parties skin and bootpack in classic Rogers style: up the Avalanche Crest Trail from the Illecillewaet side to gain the broad alpine bowl below Avalanche Mountain and Eagle Peak, then traverse and climb into the south couloir proper. Expect a mix of forest switchbacks, open bowl travel, and a final steep bootpack to a col on the Eagle–Avalanche ridge, with optional summit tag if cornices and wind loading allow.

The upper face hangs above cliff bands, so snow stability needs to be well above average before you drop. Overhead hazard from cornices along the ridge and cross‑loaded start zones is real, especially after recent storms or strong winds. The line funnels into a defined couloir with exposure to rocks on both sides; sluff management matters, and a small slide can push you toward the cliffs. This is serious alpine terrain with no easy escape once you commit.

Ideal timing is mid‑winter to early spring when coverage is solid and the south aspects haven’t gone isothermal. Watch for rapid warming, solar input, and the usual Rogers Pass artillery work—closures and control work can affect access, and unexploded shells are possible off the main trail. Check Glacier National Park avalanche bulletins, area closures, and winter permit requirements before heading out, and treat this as a full‑value day, not a quick lap.
