The Cocopah Indian Tribe is one of seven descendant Tribes from the greater Yuman language-speaking people who occupied lands along the Colorado River. Cocopah Tribal ancestors also lived along the Lower Colorado River region near the river delta and the Gulf of California. The Cocopah people had no written language, however, historical records were passed on orally or interpreted in documents written by outside visitors.
Diaries and journals kept by travelers along the Colorado River and migrants into the West documented the Cocopah people. Spanish explorer Hernando de Alarcon, a member of Coronado's marine expedition, traveled the river in 1540 and described members of the Cocopah Indian Tribe as tall, well-built people who carried wooden maces and bows and arrows. The men wore loincloths and the women wore willow bark skirts. The explorer and his crew were offered gifts of shells, beads, well-tanned leathers and food.
The Cocopah Tribe of Arizona is comprised of three noncontiguous bodies of land known as the North, West and East Reservations. Today, the East, West and North Reservations comprise over 6,500 acres, much of which is leased as agricultural land to non-Indian farmers. The Cocopah Reservation is located 13 miles south of Yuma, AZ, and 15 miles north of San Luis, Mexico, in Yuma County along the Colorado River. The reservation's unique geographical location borders the United States, Mexico, Arizona and California. www.cocopah.com, www.wikipedia.com
