The mapped surface is ground.
Estimates
- Computed effort band: easy (from length and climb; not an official difficulty).
- Estimated time 15 min one way by Naismith's rule, which assumes steady walking and adds time for climbing. Real time varies.
Before you rely on this
- No water source is mapped for this trail. That may only mean nobody has mapped one, so carry your own water.
- Check the land manager for closures, seasonal rules and permits before you go; none of that is verified here.

Length is measured from the route geometry in the source data, so it can differ from signed or official distances. Gain and loss describe the direction the line is drawn; the route view above shows the other direction and out and back. Elevation is computed from USGS 3DEP 1/3 arc-second DEM (public domain), sampled about every 10 m and smoothed.
