Abstract
Julian Steward's theory of Great Basin cultural ecology and settlement patterns has been subjected to empirical validation. Since the only data available to test this hypothesis are archaeological, it was first necessary to determine the artifactual correlates for the posited ethnographic system. These deductive propositions were determined by the BASIN I computer simulation model. On the basis of data obtained in a regional random sampling project in the Reese Valley of central Nevada, over 75% of the nearly 130 deductive predictions were statistically verified. The rejected propositions probably reflect failure of the computer model rather than shortcomings in Steward's theory. The archaeological manifestation of the Shoshonean pattern is defined as the Reese River Subsistence-Settlement System which operated in the central Great Basin from about 2500 B.C. to historic times.
