With its massive size, flat summit, and prominent glaciers, Mount Moran dominates the northern Teton Range. Although its elevation (12,605 feet) is modest, it is so large that it feels like a separate mountain range. The approach is difficult since no maintained trails reach its base.

Exum's standard climb on Moran is the CMC route. It begins with a canoe trip across String and Leigh lakes followed by a steep hike to the lovely camp, arguably the most beautiful camp in the Tetons. The climb and descent make for a long day. Climb up easy terrain to the summit of Drizzlepuss, a tower with what the guidebook describes as a "terrifying view" of the route. Rappel off Drizzlepuss, climb another 1,000 feet to the summit, climb back down the route, climb up Drizzlepuss, climb on down to your camp, descend to the canoe at Leigh Lake, and the paddle home. Private groups can also spend a second night at camp and have breakfast the next morning before paddling home. Either way, you earn your mountain!

Exum also guides the Skillet Glacier route and the exceptionally fine, though long and hard routes on the South Buttress. Descents are always complex. Despite all this, Mount Moran is many people's favorite mountain. It provides a rare combination of solitude and great climbing.
