Josh-
Click here to see the route and campsite waypoint plotted in mapsource.
Click here to see the trail plotted in google earth.
Right-click here to download a Garmin Mapsource document that contains the track logs, waypoints, etc for trails in the Sierras.
Right-click here to download a google earth .kmz file that contains all of the waypoints and tracks in the above-linked mapsource file.
BTW, I highly recommend Garmin's free upgrade to the latest version of Mapsource.
