The Winona Site in northern Arizona, near Sunset Crater, is an important archaeological complex for understanding cultural change after the crater’s eruption in 1066. First formally investigated in the 1940s by John McGregor, it yielded pit houses, trash mounds, a ball court, and pottery that he linked to Hohokam traditions, suggesting migration into a newly fertile volcanic landscape. Later research pointed instead to a more complex setting within Sinagua country, with evidence of Sinagua-style pottery and burial practices. Shell debris from jewelry-making also indicates far-reaching trade connections. Together, these discoveries show adaptation, interaction, and exchange between cultural traditions in a changing environment.
