The native plant Garden was flourishing in top photo and the bottom photo shows you the old-fashion irrigation system they used waaaaaaaaaaay back in the day. This site is Tucson’s birthplace, and archaeologists have documented 4,100 years of continuous cultivation. The Garden contains over a dozen distinct multi-cultural, ethno-agricultural heritage plots, each representing one of the many ethnic groups that farmed the Tucson Basin over the last four millennia. Crops from these plots have proven to be productive, sustainable and well-adapted to this climate and location. For more around here and the San Xavier: [ youtube video ] including the drive.

The area surrounding Sentinel Peak (‘A’ Mountain) is one of the longest known areas of continuous cultivation in the United States. Including the oldest known canal-irrigated agriculture in the United States (starting at least 3,500 years ago) and stewarded by the Tohono O’odham people.
