McGill Glades

McGill Glades sit on the McGill Shoulder above the Bostock Creek corridor in Rogers Pass, offering short, lap-friendly tree skiing on a south‑ to southwest‑facing slope. The glades are used as the lower, more conservative option on the standard McGill Shoulder ascent toward the McGill Main Chutes and Camp West, and they link back into the Bostock trail system for the exit.

From the Bostock parking area, follow the Bostock summer trail skintrack into the forest, then watch for the established McGill Shoulder uptrack branching right after the last major left‑hand switchback. This climbs through generally well‑spaced trees to the ridge. From around treeline you can drop west into McGill Glades for a sheltered lap, then contour back toward the shoulder to regain the main skintrack for another round.

The glades are popular as a lower‑exposure choice in stormy weather or when hazard is elevated on the bigger slide paths above. Still, you’re on a south‑facing shoulder that can be thin, crusty, or icy after warm or clear spells, and the approach often feels like a grind for the length of the skiing. 

McGill Glades lie inside Glacier National Park’s winter permit system. Check the Rogers Pass winter restricted and prohibited areas, daily avalanche bulletin, and current access status before heading out, and carry the required winter permit if your route crosses any restricted zones. Full regulations and daily maps are posted by Parks Canada at the Rogers Pass Discovery Centre and online: Parks Canada – Glacier National Park.
