Starts at a derived trailhead (2 mapped trails start within 150 m), no mapped parking within 400 m; the route starts at the nearest mapped trail junction, 62 m from that point. Built by Arête from the graph of mapped trail segments (OpenStreetMap). Segments join where their ends are within 12 m of each other or one ends on another's line (a T-junction). A loop returns to its start without repeating a trail section; an out-and-back goes to a mapped trail end and returns the same way, so its length counts both directions. Names come only from the mapped trails it uses. Length is measured on the joined line; elevation is computed from USGS 3DEP. Not an official or recommended route.

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.
