I succeeded, then found that there were other GPS tracks available for Utah, Colorado and Arizona as well. I was able to convert them to .kml format much more easily and thus was born some of the offroad trail maps which I was able to make available. Of course, much has been added since then.
Recently I found one of the books which some of the tracks came from and have been able to greatly enhance some of the California maps: California Trails Desert Region by Massey, Wilson and Titus.
The California desert region now has alot more detail, especially for those GPS tracks where petroglyphs (a particular interest of mine) are concerned.
I am not the same having seen the moon shine on the other side of the world.”
HOWEVER, although I have verified that the waypoints given do actually seem to have a basis in fact, i.e. are visible on the satellite image, I don't consider them "verified" until someone actually rides them with a GPS unit. (hint, hint).
Those of you in California, or who are going there, take a browse on over to OffroadingHome.com and look at the "California Trails" map in Google Earth.
Pick a trail which interests you, ride it and send me your track! That way I can mark it off as "verified by ride" and give you credit for the verification, How about it?
