One of Colorado's finest, this demanding ski descent provides a very worthy day. From the broad snowfield North of the summit the route drops, drops, then drops again into a steep 50' wide slot through the cliffs that finally spits you out near a ditch with a faint trail on the right. To return to your car follow the ditch trail East but keep a sharp eye out for a short climb, above the ditch on the right, to reach the established trail. Continue East around Buffalo on a well established trail to return to the trailhead.
Head North from the summit of Buffalo and into the steep funnel that drops you into the couloir.
This is best achieved after the snow consolidates in the Spring. Climb early while the snow is frozen and time your descent to catch the corn.
Don't even think about it if things don't freeze up solid overnight before you go. Wet slab avalanches are about as destructive as boxcars tumbling down the couloir!
