University Indian Ruin (UIR), located in the eastern Tucson Basin, is a prime example of a Classic period Hohokam platform mound archaeological site. The extent of the UIR site has long been understood to stretch beyond its administrative boundaries. This research investigated the UIR site boundary using Identification Testing and provided a new, larger border to the site. Results from surface and subsurface investigations also indicated a longer occupation at University Indian Ruin than was previously understood – stretching back to at least the Pre-Classic period. Collaboration with local residents on the project led to the donation of artifacts from a private residence that improved the conclusions presented here.

位于图森盆地东部的印第安废墟大学（UIR）是经典时期Hohokam平台土墩考古遗址的一个典型例子。长期以来，人们一直认为UIR网站的范围超出其管理范围。这项研究使用“身份验证测试”调查了UIR站点边界，并为站点提供了新的较大边界。地表和地下调查的结果还表明，在印度遗迹大学期间的居住时间比以前理解的要长-至少可以追溯到前经典时期。与当地居民在该项目上的合作导致私人住宅捐赠了文物，从而改善了此处提出的结论。
