Wild Horse Pass and Vee Quiva are the two facilities that comprise the Gila River Casinos. Gaming also continues to be a positive economic development activity for the Community (see below). One park, Lone Butte Industrial Park, is nationally acclaimed as one of the most successful Indian industrial parks in the U.S. The Community currently operates three industrial parks that are home to several local and national companies. The Gila River Indian Community is steadily increasing and diversifying its industrial, agricultural, retail and recreational economic base. Tribal administrative offices and departments are located in Sacaton. The 372,000 acre reservation, which lies south of Phoenix, Tempe and Chandler, was established by an act of Congress in 1859 and formally established by Constitution in 1939. Composed of two members of tribes, the Pima and Maricopas, GRIC is located in south-central Arizona. The Gila River Indian Community (GRIC) traces its roots to the Hohokam, prehistoric Indians who lived and farmed along the Gila River Basin centuries ago.
