Multiple stops on the Old Spanish Trail

There are probably 50 stops in six states for this trail:  justifiably so- it was a long and important one:

On this trip, I got stamps at 4 locations in Barstow, California, One at the Mojave Desert Preserve, two near Las Vegas, the BLM office and Red Rocks, and also at Lake Mead in Nevada.  

For the BLM office in Nevada:  

Several stamps plus the Trail stamp at Red Rocks outside of Las Vegas:

One at the Alan Bible VC at Lake Mead in Boulder City NV:

One at the Mojave HQ in Barstow:

And several at the 3 other stops in the Metro Barstow area:
