Formative period archaeological sites in west central Colorado have stimulated debate and discussion related to their archaeological cultural classification. Comparisons with recent artifact re-analysis, as well as other research from neighboring areas, suggests that pan-Ancestral Puebloan culture influenced this area from 200 BCE to 1200 CE, most specifically in the Mesa Verde region. While some researchers have advocated for a Fremont cultural classification, others have attributed these areas to the Gateway culture. What is clear is that this area saw interaction resulting either from trade/emulation or developed out of an earlier migration into the area. West central Colorado then presents to the archaeological community a unique study area where southwest connections had a great influence.
