Sunset Crater north of Flagstaff.
Their utensils and habits were similar to those of the Hohokam, though different in some respects. For example, in contrast to the Hohokam practice, the Sinagua polished their plain brown pottery. Also, it is known that after 1070, they buried their dead in an extended position instead of cremating them as the Hohokam did. Although the Sinagua were basically farmers like the Hohokam, at this time they depended to a greater extent on foods they gathered and meat they hunted than they did later.
About 1070, some of the Hohokam left the valley. Evidently many of these emigrants went north to the plateau region east of present-day Flagstaff, to plant in the moisture-conserving ash-fall area created by the eruption of Sunset Crater in 1064. Shortly after these Hohokam departed, many of the Sinagua moved down from the hills into the middle of the Verde Valley. This occurred about 1125. They lived much as they had before, but with two important changes: they adopted the Hohokam idea of irrigation, and they began building surface houses of rock and mud—an idea acquired from still another group, the Pueblo Indians, farther north. These Sinagua were the people who built the stone pueblos we find in the valley today.
At first they erected small settlements on well-drained ridges overlooking their farmlands. Occasionally, also, caves were utilized for dwellings; the first 3 or 4 rooms of Montezuma Castle were evidently built in the 1100’s.
From 1125 to 1200, the settlement at Montezuma Well was increased by groups of these Sinagua Indians who had left their homes in the foothills to the north and east. It appears that they joined some of the remaining Hohokam, as several customs of the latter survived up to 1400. In this period the Sinagua also utilized caves near their fields, and built a small pueblo on the west rim of Montezuma Well. Limestone rock for their masonry was available on the rim of the Well, and river boulders for foundations were taken from the creek. Mud and clay, which they mixed for their mortar, were easily obtained along the creek.
Ancient irrigation ditch near Montezuma Well.
As the years passed, more land was put under cultivation and more ditches were constructed. To insure adequate care of their farmland, 1- and 2-room “farm” structures were built on the slopes above and along the course of the main ditch. From these, the occupants were able to view the fields while irrigating and also could divert the water from the ditch below them whenever necessary. At their peak, the people at Montezuma Well were farming about 60 acres, or possibly more, and their main ditch was about 1 mile long.
