• CULTURE HISTORY AND PREVIOUS WORK Prehistoric Overview A variety of site types are present in the general project area, representing most of the thematic contexts outlined in the original RP3 documents for Northwest Colorado (Grady 1984; Mehls 1984) and in the more recent prehistoric contexts for the area by LaPoint (1987), and Reed and Metcalf (1999). Prehistoric sites in the general area include lithic scatters, open campsites, quarry sites, rockshelters, and rock art panels. Evidence of Paleoindian inhabitants in the area consists of a few isolated projectile points including at Cody Complex points at 5RT139. Archaic -age lithic scatters and open camps have been recorded in the area as well as some rock art panels believed to be Archaic in age. Excavations at the Red Army Rockshelter (5RT345) located a couple miles to the west recovered evidence of multiple occupations spanning the Pioneer Archaic through Protohistoric, including two house structures within the shelter (Pool 1997). Numerous Formative Era Aspen Tradition age lithic scatters and open camps have also been recorded in the general, area, as have Protohistoric and Historic Ute or Shoshone rock art sites. In the Northern Colorado River Basin, the prehistoric sequence has been divided into four broad eras, each of which is further divided into time periods, traditions, or phases (Reed and Metcalf 1999). The eras are Paleoindian, Archaic, Formative, and Protohistoric (Table 1).
