In 1993, the Village Mapping Project was initiated to obtain detailed surfacial information about Pueblo II–III villages outside the Sand Canyon locality. Thirty villages were initially mapped using orthorectified aerial imagery. Six of the 30 centers were then chosen for intensive mapping, architectural analysis, and a chronological analysis of pottery sherds on the modern ground surface: Albert Porter Pueblo, the Bass Site Complex, Seven Towers Pueblo, Cannonball Ruins, Woods Canyon Pueblo, and Hedley Main Ruin.
