Corner Mountain Trailhead the Forest Service's write-up
Photo: US Forest Service
Winter cross-country skiing and summer hiking trails. In the winter for cross-country skiing it accesses the Corner Mountain Loop (2.3 mi/3.8 k), Camp Loop (1.3 mi/2 k), and Spruce Loop (0.4 mi/0.6 k), as well as the lower end of the Barber Lake Trail. This area offers an interconnected set of trails with rolling terrain and several steep sections.
The lines are the US Forest Service's National Forest System trails layer (public domain), read 2026-10-16 and simplified for the map; the length is the line's, end to end, and the class, surface, grade and tread width are the forest's own entries where it publishes them - a forest that publishes the centreline alone has none. The trailheads and the points along the way are the Service's recreation points, and the write-ups its own recarea text, unedited. Heights come from USGS 3DEP through Terrain Tiles on AWS (Mapzen/Tilezen), read along each line and rounded; a short trail on steep ground can be off by a few tens of feet. Closures change: check the forest's own site before you go.
