Δ Cumberland Trail elevation profiles based on 10m and 3m DEM elevation data from USGS NED server

The GPS data is used for fetching and plotting the USGS elevation data. Due to the dicretization of the GPS track data, the track length is usually 4% or more shorter than the actual trail length. For example the wheeled length of the Piney River trail is 8.46 miles, while the GPS track length is 8.1 miles (which includes adjusting for elevation "distance"). The cumulative +climb/-descent is calculated from the USGS elevation data and is smoothed by a 10' filter, but even still the estimates are probably quite high. (Elevation data collected by the GPS is typically less accurate than fetching the USGS elevation data.)

Based on the elevation data, the steepest half-mile sections are Lawson Mtn (mile 2.2 to 2.7 25%, 6.5 to 6.9 23%, 3.6 to 4.1 22%), Arch Mtn (3.6 to 4.1 22%), and Cross Mtn (12.2 to 12.7 22%).
