Elevation along the trail from start (left) to end (right) as drawn. Values are computed from USGS 3DEP 1/3 arc-second DEM (public domain), sampled about every 10 m and smoothed. Walking the other way reverses the climbs and descents.

Length is measured from the route geometry in the source data, so it can differ from signed or official distances.
