 Farming terraces on the mesa wall behind Chetro Ketl may have been used for growing specialized crops such as tobacco, and canals running from Pueblo Bonito to Chetro Ketl probably carried rain water.Chetro Ketl's position in downtown Chaco and its proximity to South Gap further aided agricultural efforts near the great house, as summer storms tended to linger in the opening, funneling moisture to the area.There is no obvious visual evidence of the linear features usually associated with farm fields in the land surrounding Chetro Ketl, but in 1929 aerial black-and-white images by Charles Lindbergh revealed what appeared to be a rectangular plot.
