Burro Schmidt Tunnel is locate in the remote El Paso Mountains in the Mojave desert. I have traveled there several times over the last 20 years or so. I decided to go back yesterday. It's a rough drive that sometimes requires 4WD. There's tons of interesting info all over the web about this place. Here's a couple with some different info on both. If you read this first link, make sure to follow the link at the very bottom of the page for more updated info. http://www.high-desert-memories.com/garlock.html http://www.burroschmidttunnel.org/ The tunnel pics are looking in and out from the same spot. I didn't make the journey through the tunnel yesterday.
