About San Rafael State Natural Area

San Rafael State Natural Area is a unique area with rolling hills, native grasses, and oak and cottonwood trees. This beautiful valley is the headwaters of the Santa Cruz River, which flows into Mexico then turns north back into the United States and eventually joins the Gila River. The riparian areas and native grass prairie are home to many species of plants and animals. One of the endangered plants, Huachuca Water Umbel grows in the river area. One can also see mule deer, javelina, antelope, bobcats, cougar, coyote, and many birds unique to the prairie.

ABOUT THE RANCH

The San Rafael Valley was identified in the early 1970s as a proposed natural area because it represented one of the finest stands of native grassland in the State.
