Mount Thomas TH #1870 the Forest Service's write-up
The Mount Thomas trail begins near Crooked Creek Pass and ends at Forest Road #514. The trail begins with a moderately steep climb through spruce/ fir forest before leveling out to follow the Red Table Mountain ridge and climbing the peak of Mt. Thomas at 11,977 feet. The trail then travels through an alpine zone becoming rocky with little vegetation, and after about 7 miles the trail descends into sparse stands of spruce/fir forest and ends in a large meadow that connects with Red Table Mountain Road #514. The Mt. Thomas trail’s best features are the panoramic views seen in all directions.

About this trail's facts
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.
