The least technical way up the highest point in North Cascades National Park, reached via a remote approach from the Stehekin side rather than the more heavily climbed Northeast Buttress.
Access is via Lake Chelan: take the passenger ferry to Stehekin, then the seasonal shuttle bus (or a long walk) up the Stehekin Valley Road to the Park Creek Trailhead, around 2,300 feet. From the trailhead, the Park Creek Trail climbs steeply for its first stretch above a gorge where Park Creek meets the Stehekin River, then levels out through the Goode burn area for several fairly flat miles past Five Mile and Buckner camps. From the head of this basin, leave the maintained trail and follow a faint climbers' path up toward the south side of Goode, gaining several thousand feet to a high camp below the peak's south face. From camp, ascend to a notch that accesses the couloir system on the southwest side of the mountain. The couloir, first climbed in 1936 and still the least technical line on the peak, is a sustained gully climb with real exposure; parties emerging from its top cross toward Black Tooth Notch and the upper northeast face to reach the true summit, since the summit block itself involves further scrambling that can approach low Class 5 depending on the exact line taken.
Descend the climbing route, taking care in the couloir's loose rock; multiple tracks exist below the couloir exit and it is worth noting which one was used on the way up, since it is easy to end up on a harder line during the descent.
