The Land Hill and Hidden Hills study areas were the site of the 2006 and 2007 Brigham Young University's archaeological field schools. The two study areas are located in contrasting environments; the Land Hill area is located along the Santa Clara River in southwestern Utah, and the Hidden Hills area was is located on the Shivwits Plateau in northwestern Arizona. The Land Hill study area is located within a well-watered environment which would support a primarily horticultural lifestyle. The Hidden Hills study area is located in an arid environment without permanent streams which would support a more mobile hunting lifestyle. The contrasting environments of these two study areas allowed for a study of the similarities and differences in the use of stone tools. Based on the results of the analysis and comparison of the stone tool and debitage assemblages, from sites in both areas throughout time, suggests that the people in the Land Hills study area actually seemed to be living a lifestyle similar to the people in the Hidden Hills area.
