This many-roomed pueblo sits on top of a signifant 'rise or hill' overlooking the surrounding river valley. The very green-looking land, visible in several of the vista shots, shows how water-filled, almost swampy, the low-lying land was here. This was significant because most of the farming techniques known, previous to the occupation of this 'hill' was 'dry land farming'--dependant on rainfall for growing---needed moisture for their crops of corn, squash and beans. They, like the Hohokahn [in southern AZ, that I previously spoke/wrote about] developed a system of irrigation canals, diverting the river water to the crop-growing areas--very novel idea in those days, people, and the beginning of useful knowledge still utilized today!!!
