Murray Springs Clovis Site, Archaeological site near San Pedro River, Arizona, United States.

Murray Springs is an archaeological site near the San Pedro River in Arizona where researchers found remains of mammoths, bisons, horses, and camels dating back about 13,000 years. The bones and stone tools lie along an ancient riverbed and show different hunting and processing areas.

In 1966, C. Vance Haynes and Peter Mehringer of the University of Arizona found two concentrations of mammoth bones while extending the mapping of the Lehner Mammoth Kill Site, 19 km south. Excavations funded by the National Science Foundation and the National Geographic Society followed from 1967 to 1971. The site was declared a National Historic Landmark in 2012.

The Clovis camp at Murray Springs was a base for hunting mammoth, bison, horses and camels around 11,000 years BP. Excavations from 1967 to 1971 uncovered hearths, projectile points, lithic tools and debitage, plus a bone tool thought to be a shaft straightener. A single pot sherd found on the surface shows later use of the spring between about 1300 and 1450 CE.

The site is easy to reach from Route 90 if you head east from Sierra Vista and then follow the signs. It's wise to wear comfortable shoes and be prepared for desert weather conditions in the area.

A single pot sherd found on the surface shows the spring was used again around 1300 to 1450 CE, long after the Clovis camp. The site's analysis also argues against the extraterrestrial impact theory of the Pleistocene extinction.
