History of South Mountain Park

The story of South Mountain Park begins with a vision that predates the modern sprawl of Phoenix. In 1924, when the city was still finding its footing, civic leaders recognised the need to preserve the dramatic mountainous landscape to the south. With the blessing of President Calvin Coolidge, the city acquired thousands of acres for a remarkably low price. This decision saved one of the most beautiful tracts of Sonoran Desert from potential development, ensuring that generations of Arizonans would have a wild, untamed backyard. During the Great Depression, the park gained its character through the sweat and grit of the Civilian Conservation Corps. These workers were sculpting a landscape. They carved trails and constructed stone structures that blend so seamlessly with the mountainside that they seem like natural extensions of the rock itself. Their work transformed a rugged expanse into a functional recreation space, providing a legacy of public access that remains the envy of major cities across the globe. Today, the park stands as a testament to the relationship between urban growth and nature. While the city of Phoenix has expanded to wrap its arms around the park boundaries, the interior remains a pristine desert ecosystem. It serves as a living laboratory for biologists studying the unique chuckwalla populations and a sanctuary for hikers seeking silence. By stepping into South Mountain, visitors are stepping back into the ancient rhythm of the desert, preserved forever by the foresight of those early planners.
