The grassy San Rafael Valley sits right along the Mexican border in Santa Cruz County, Arizona. It is a high, intermontane valley that, because of the excellent stewardship of the local ranchers over the years, survives largely intact as a grassland ecosystem. The range has not suffered the degradation often seen elsewhere, such as invasion of exotic weeds or cactus, and has not been overgrazed. This photograph shows where the eastern reaches of the valley meet the western slopes of the Huachuca Mountains.
