In the winter of 1934–35, a ball-court, analogous in many details with those of Central America, was discovered at Snaketown on the Gila River Indian Reservation in south-central Arizona, during excavations conducted by Gila Pueblo. The announcement of a ball-court 1500 miles from its supposed origin, and in a region where it was entirely unexpected, met with skepticism until the discovery was verified by men qualified to judge from first hand knowledge acquired in the Middle American field. A new angle to the problem of relationships of Southwestern, Mexican, and Central American cultures was thus brought to the fore. Now, to add to this discovery, comes another find in the form of a rubber ball. It, too, was found in south-central Arizona and may, indeed, have been used in the game for which the courts were built.
