Montezuma Well is a natural limestone sinkhole 470ft wide, surrounded by both Sinaguan and Hohokam dwellings. Water from the well was used for irrigation by the Native Americans and is still used today by residents of nearby Rimrock. Access is from I-17 exit 293, 4 miles north of the Montezuma Castle exit. Follow the signs for another 4 miles through McGuireville and Rimrock.
