The next day I started out on I-15, but soon after entering California, I took a left off the freeway and entered the Mohave National Wildlife Preserve. Wonderful desert desolation, but 50 miles or so in, I discovered the restored Kelso Depot, in an otherwise abandoned town (well, a few operational buildings).
Apparently, Kelso had some importance as a railroad hub during World War II, and before that as mining shipping point and engine addition for the steep grade into Vegas.
A wonderful find... now the depot serves as a visitor center for the Mohave Preserve.
Leaving Kelso heading to Amboy, I ended up on a stretch of Route 66.
Just outside Amboy is the Amboy Crater, easily visible out of the desert landscape.
The road would often rise to a high pass before descending into another vast valley. At one high point, I found a cool, rock mountain.
At another pass, I found a great view back into the desert. This from a curious "rest stop".
Eventually I ended up in 29 Palms and joined the major highway to Palm Springs, and then to Orange County. I so enjoy "leaving the pavement" of a boring Interstate highway and exploring alternate routes. So much to see and to experience, with many surprises.
