On June 21, 2011, I surveyed the trails in the recently-opened Ramona Grasslands Preserve on my mountain bike. On a previous visit to the trailhead on June 17, I took a few pictures and noted the latitude and longitude of the trailhead parking area.
The topographic map is of limited use because many roads in the area were built or moved after the most recent revision. In particular, Archie Moore Rd. has been moved.
