Excerpt from Some Hot Springs of Southern California: Their Origin and Classification In the changes that took place along the fault line the Perris Valley was raised slightly; the San Bernardino Range was raised much more; and the San Bernardino valley sank until portions of it were below sea level.

The waters of the Arrowhead Hot Springs, and of others on these fault lines, began to flow soon after the fissures were formed. In other words the hot springs are as Old as the San Bernardino Range itself. That means that the hot springs are Older than Niagara Falls, older than the Pyramids of Egypt, Older than the Big Trees of the Yosemite, and older than the aboriginal Cave-man. They are just as permanent as the mountain itself. This brief summary of a study of the origin of some of the hot springs of southern California suggests that the geologic study of all the hot springs Of the State should be made for the benefit Of the people.
