Bugs to Rogers Traverse

Mega-classic high-alpine traverse linking the Bugaboos in BC Parks to Rogers Pass in Glacier National Park. Expect big glaciation, cols, and occasional technical steps (Deville Headwall often requires rappels) with exposure to seracs and cornices. Slopes commonly run in the mid-30s; plan for consequential 30–38° terrain and long days in complex route-finding. Wind slabs and overhead hazard are routine; crevasse rescue competence is mandatory.

Access south end (Bugaboos): winter roads aren’t maintained; you’ll typically ski the road to the summer lot or arrange a permitted heli—snowmobiles are not allowed in the park, and the Conrad Kain Hut is closed Nov 16–Apr 30. North end (Rogers Pass): park only in designated winter lots and secure the required Winter Permit and overnight parking permit before entering restricted areas due to active artillery avalanche control.

Best window is spring when bridges are stronger and weather improves (commonly mid‑March to mid‑May). Plan camps/huts around stable weather; Glacier Circle Cabin is a strategic shelter on the Selkirk side but still demands full mountaineering skills. Pros: all-time line, efficient glacial benches, occasional huts. Cons: closures/logistics around Rogers Pass, technical cruxes with overhead hazard, zero margin in storms.
