This area is Open

The Frost Mountain Trail begins at Shoestring Lake Trail #1385 and ends at South Fork Taneum Trail #1367.

SETTING: Clearcut, ridgetop, open hillsides, old-growth trees, stream.

Heading north, the trail begins climbing immediately through a large clearcut (1989) for about 0.5 mile with Frost Mountain to the right, crosses a divide and begins a rapid descent to the South Fork Taneum Creek, which the trail crosses before ending on trail 1367 South Fork Taneum. Portions of the trail were reconstructed in 1979, but the trail is mostly steep and rugged. South from the trailhead, the trail follows the 3100-124 spur road for about 800 feet before heading off to the left into forest. The trail continues on a gentle up and down grade through trees, meadows and clearcuts for about a mile to its end at a junction with Shoestring Lake Trail 1385.
