An excellent ski mountaineering line on Webster, Horseshoe is like an easier version of Shoestring. Start from Webster Cliff Trail and skin past the base of Shoestring Gully. Follow blazes for a few more minutes to the inobvious base of the drainage. From here, skin up through dense woods to gain the runout of the gully. A boulder field that is thankfully shorter than Shoestring and Landslide leads to the base of the first ice bulge. This can be skirted to climbers left, climb a long section of snow to another ice bulge, before reaching the base of a narrow rock slot. This is the only mandatory ice bulge, and presents the crux at WI2. Climb a few funky bulges into the steep upper gully, which ends at a prominent rock buttress, the drainage above is choked out with bushes. Drop in and enjoy steep turns to above 20 feet above the ice choke, traverse skiers right to a good spruce tree. As of 2025 there is a blue dyneema sling with a locking carabiner on it for a rap anchor. A 20m rappel gets you over the rock band, you may need to downclimb some low angle ice to reach the snow again. From here, enjoy excellent chute skiing in a beautiful setting, skirting the next few ice bulges easily to skiers right. Exit the boulder filled runout and skin back to the car.
