Twenty Mule Team Canyon
This canyon was named in honor of the 20-mule teams that, between 1883 and 1889, carried 10-ton loads of borax through the burning desert (though they didn't actually pass through this canyon). Along the 2.5-mile, one-way loop road off Highway 190, the soft rock walls reach high on both sides, making it seem like you're on an amusement-park ride. Remains of prospectors' tunnels are visible here, along with some brilliant rock formations.
