“This is a gradual climb through conifer forests and open tundra.”— J. Bella
From Williams Lake, head south on the west side of the lake. Climb through some low-angle trees onto a flat basin, traverse across an open wetland known as The Bog near the bottom of two large avalanche paths. From the far side of The Bog, make a couple switchbacks to treeline and leave the trees, entering the alpine at a series of rolling glacial moraines on Sin Nombre's north slopes. Trend slightly to the southeast as the terrain levels out, then climb the slopes to the obvious saddle between Sin Nombre and West Simpson.
