Interstate 15, Arizona, California, Idaho, Montana, Nevada and Utah
After climbing out the L.A. basin I-15 crosses the impressive Mojave Desert to Las Vegas. I-15 is mainly flat between L.A. and Las Vegas with only one extremely easy mountain pass. Picture (32KB)
Between Las Vegas and St George I-15 climbs through the narrow and magnificent Virgin River Gorge. The bulk of the run through Utah is through arid semi-desert; beautiful in its own bleak way. This unforgiving country certainly makes you ponder on what life must have been like for the pioneers who first crossed it in covered wagons.
