Hole in the Ground

This is a famous mountain bike loop near Donner Summit (Truckee, CA). It is mostly single track and fairly technical, with many rocks, roots, and switchbacks. I pulled the data from my Forerunner 305 using garmintools and generated a Google Maps overlay with the help of the garmin_gmap utility, which is part of the garmintools package. There are various descriptions of this trail on the web, but there are few (zero?) GPS-accurate maps of the route.
