Picacho Peak State Park is a state park surrounding Picacho Peak in Picacho, Arizona. The park is located between Casa Grande and Tucson near Interstate 10 in Pinal County. Its centerpiece spire is visible from downtown Tucson, a distance of 45 miles (72 km). The summit rises to 3,374 feet (1,028 m) above mean sea level. Though appearing to be the remnant of a volcanic neck, it is now believed to be a tilted and eroded piece of rock overlain by a lava flow.
