The North Branch of Ammo is a unique line that unfortunately doesn’t always form. NW winds frequently scour this area, preventing a snowpack from developing. The North Branch offers mellow, yet adventurous skiing. Start by skiing up the Cog Railway. Above Jacob’s Ladder, traverse right following the cairned West Side Trail into the heart of the gully. Surprisingly low angle skiing in the upper gully, slowly steepens and funnels into a series of cascades. The lower half consists of tree lined gully skiing with a series of convex rolls. These rolls often present ice bulges that can be traversed around in the trees to either side. Negotiate these little rolls and cruxes until you reach the creek bed below. Ski out to where it joins the South Branch, and follow this back to Ammonoosuc Ravine Trail.
