1.3-mile loop hike down a ravine to the second spring along the east-west Mojave Road route. As at the other springs, this too was the site of a military outpost from 1866 - 1867 to protect the U.S. Mail and supply route across the desert. At the beginning of the hike there is an interesting stone structure called the Rock House, made from rocks in the surrounding area. It was built in 1929 by a man named Bert George Smith, who was recovering from exposure to poison gas during World War I. He thought the desert environment would help him regain his health. Well, I guess he was right, because although we was expected to not survive long, he lived in this house for 25 years.
