About 12 miles north of Sentinel and I-8, Agua Caliente Ranch hosted guests for it's hot springs starting in the 1870's, and became a resort by 1897. The hot springs were used by Native American's long before the American West was settled.
Agua Caliente was a popular resort, with 22 rooms and a pool which collected the hot waters from the spring. Today, the springs have dried up and there's not a lot left. However the resort still stands, along with some other ruins. Photo by Kathy Weiser-Alexander.
