Lavatube, Mojave National Preserve Originally uploaded by Mastery of Maps I knew it. There had to be cool underground features like these lava tubes & caves out there. Jesse & I searched but did not find. Been out to Mojave Preserve six times. We'll hafta keep looking. Vast spans of Mojave desert encompass historic mines, buildings, railroads, mountain peaks, boulders, joshua trees, pinyon pine forests, caverns and caves, lava tubes, sands dunes, dirt roads and a new, totally restored Kelso train depot - out in the huge triangle of land, east of Barstow . Near Interstate 40, Interstate 15 & the Nevada state line. Way out there in the middle of freakin nowhere near Kelso, Cima & Kelbaker Rd. For best results arrive in day light hours when first visiting this unfamiliar desert region. It's easy to get lost without light or without a GPS. Maps are only as good as the ones you brought and how bright your dome light is in the car. Don't rely on c
