The route in 3D
USGS and partner elevation data build the terrain, and the US Forest Service centerline draws the route.
0.4 mi · Typical grade 0 to 5%
Length is the trail as the Forest Service maps it, not a trip distance. Hike out and back and you will cover it twice; check the shape of the route before you count on the figure.
This record is a snapshot of U.S. Forest Service data retrieved on 2026-07-09. It does not reflect current closures, conditions, or seasonal orders. Check with the local ranger district before you go.
Estimates, derived from USGS elevation data sampled along the USFS-mapped route, computed 2026-07-10. We have not measured these figures in the field.
A day here means a typical grade of 0 to 5%. Tell the Trip Builder where you are headed and it assembles a day-specific kit with weather, daylight, and terrain in mind.
