The North Face is a documented alpine route on Granite Peak and is generally regarded as a more serious objective than the standard couloir lines. It involves steep, exposed climbing on snow, ice, and mixed terrain, with objective hazards typical of high alpine faces. The route is highly condition-dependent and may require technical protection and solid route-finding. Because of its seriousness, it is usually attempted by experienced climbers with alpine skills. Published sources describe it as a legitimate mountaineering route rather than a scramble or hike. Precise quantitative details are not reliably documented in the sources I can verify, so they are omitted.
