Okay, here is essentially what would be the 4th and final section of the East Mojave Heritage Trail. This was a weekend trip and we based out of Amboy, California. The route is from Amboy to Needles the first day and then returning by a different route than next day. This includes the tracks that we actually rode as well as the rougher route that I laid out to guide me through. The true East Mojave Heritage Trail is actually the first day section from Fenner to Needles. Everything else is just interesting side trips. One of the tracks chose a route through the Turtle Mountains which is now actually WILDERNESS and not open to motorized vehicles. You can use the route as a go around for the wilderness. The sidetrip on day 2 that goes up Carbonate Gulch is a rough route to a abandoned mining operation which is pretty cool to explore.
There is also a sidetrip on the first day to the area where Camp Clipper used to be near Essex and Fenner. This was one of General Patton's tank training bases. If you look closely at Google maps or Google Earth you can see remnants of the sizable road grid that used to be there
We gassed up in Fenner (both ways) , Havasu Lake (on the reservation), and Needles.
Other questions welcome.
