Montezuma Hot Springs

Montezuma Hot Springs, also known as Las Vegas Hot Springs, are a grouping of 20-to-30 thermal springs in the Montezuma unincorporated community of San Miguel County, near the town of Las Vegas, New Mexico.
History.
The springs were used for centuries by local indigenous people for their healing properties. After New Mexico was annexed in 1846, the U.S. Army built a one-story adobe-constructed hospital at the site of the hot springs, that was later converted into a hotel in 1862, called "The Adobe".
In 1879, a group of "eastern promoters" raised funds to build a second hotel, the "Hot Springs Hotel" on the land adjacent to "The Adobe Hotel". The new hotel contained two bathhouses – one for hot mineral water soaking and one for mud baths. In 1880, the Santa Fe Railroad created the Las Vegas Hot Springs Company; the company purchased the Hot Springs Hotel, the surrounding property and the bathhouses. In April 1882, the company completed a narrow-gauge track between Las Vegas and the hot springs, and the first train made the journey on April 5. The company continued to develop the property and later that year opened the three-story Queen Anne styled "Montezuma Hotel" featuring 270 steam-heated rooms. In January, 1884, the hotel and bathhouses burned to the ground; within weeks the Santa Fe Railroad and the Chicago-based architectural firm of Daniel Burham and John Root were crafting designs for a new, grander hotel, completed in 1885. Within four months of opening, the second Montezuma Hotel burned, leaving the stone walls of the lower two floors. It was rebuilt for the third time, opening in August, 1886, and formally renamed the Phoenix Hotel, although the name Montezuma Hotel remained in use.
Folklore suggests that Billy the Kid and Jesse James used the springs after playing cards in a nearby old adobe building.
Description.
There are three groupings of concrete soaking pools with sand and gravel bottoms of differing depths. Volunteers scrub the pools every two weeks, and there is a constant flow of fresh spring water that keeps them clean. The hottest pool, known as "The Lobster Pot" has been landscaped and sculpted into a hillside, another pool, known as "The Cube", sits near the ruins of the old bathhouse, while the third grouping consists of two concrete pools, known as "The Toaster". There are also several seeps nearby where the mud can be dug out to create primitive soaking pools.
Water Profile.
The hot spring water emerges from the ground at 138°F (59°C). The water temperatures in the soaking pools vary from 94°F to 120°F. The source of the spring water issues from fractured rocks at the intersection where the Gallinas River crosses the Montezuma Fault. The water contains relatively dilute solutions of sodium-chloride-bicarbonate-sulfate, with moderate silica levels and very high fluoride levels (≤23 ppm). Compared to nearby hot springs, Montezuma mineral water contains less natural chloride and higher levels of bicarbonate and sulfate.
Location.
The hot springs are located across from the Gallinas River, now on the property of the Armand Hammer United World College former site of the Victorian hotel known as "Montezuma's Castle" which now serves as the college administration building.
