Pajarito Mountains

The Pajarito Mountains is a small mountain range of western Santa Cruz County, Arizona, United States, which extends south into Sonora, Mexico. The range is adjacent to the Atascosa Mountains at its north, with both ranges in the center of a north-south sequence of ranges called the Tumacacori Highlands. The Highlands have the Tumacacori Mountains at the north, and south of the U.S.-Mexico border, the Sierra La Esmeralda range (the Emerald Mountains). The Tumacacori Highlands are part of a regional conservancy study of "travel corridors" for cats, called Cuatro Gatos, Four Cats, for mountain lions, ocelots, bobcats, and jaguars.
