Trail #234 Ape Canyon

Beginning next to the mudflow that traveled down the Muddy River drainage, the trail climbs steadily through a plantation of young trees before entering groves of giant Douglas fir, silver and noble fir. The trail then emerges on an open ridge top with views east into Ape Canyon and in the distance, Mount Adams. Wildflowers, when in bloom, paint these meadows in vibrant colors. Continuing along the ridge, the trail passes through patches of 1980 standing dead forest before emerging at the top of Ape Canyon, where it terminates at the junction with Loowit Trail #216.
