A TOPO! gps file can be downloaded from 14ers.com and used by National Geographic's TOPO! software which is discontinued but still used by many people. It's compatible with most GPS units for exchanging route and waypoint information between your computer and GPS unit.
Each TOPO! file contains a line which was plotted using the "tracking" feature of a GPS, while hiking the route. Once opened in the TOPO! software, you can customize the data by adding waypoints or other information before uploading it to your GPS.
Notice: The files were created in TOPO! version 4.0 and may not be compatible with some previous versions.
