Casa Grande National Monument ruins shed insights into primitive life in the Desert Southwest

Roughly translated, Casa Grande means great house. If you visit Casa Grande Ruins National Monument near Coolidge, AZ you’ll definitely see the “great house” and so much more.

Prior to my visit in 2019, I had seen numerous pictures of the Casa Grande Ruins site – mostly of the “great house” alone. What impressed me when I went is how expansive the entire site is and how many ruins are still present.

As I strolled the grounds, it was easy to envision a time when the location was bustling with the activity of hundreds of people.

Archeologists have uncovered evidence that the ancient Sonoran Desert people who built the Casa Grande also developed wide-scale irrigation farming and extensive trade connections. Apparently trade went on for over a thousand years, until about 1450 A.D.

Findings include earthen buildings, red on buff pottery, and extensive canals consistent with the Hohokam people known to have inhabited this area.

According to the National Park Service website, Hohokam is an O’odham word used by archaeologists to identify a group of people who lived in the Sonoran Desert.

Based on interpretations handed down over centuries, Hohokam is believed to be a term that loosely translates into “all used up” or “those who are gone”.

How Casa Grande rose to “Greatness”

As the ancient Sonoran Desert people expanded between 600 & 900 A.D., their contacts with neighboring tribes greatly increased. Trade flourished, bringing material goods and ideas from far and near.

They imported turquoise, pottery, pinyon nuts, obsidian (volcanic glass) and even sea shells from the Gulf of California and the Pacific Coast. From Mexico came copper bells, iron pyrite mirrors, and parrots.

And what did these desert dwellers have to offer in exchange? Their farms produced surplus crops for export. They also traded their finely crafted shell jewelry and pottery. Casa Grande Ruins became a crossroads in the trade system.

One major route, reconstructed by archaeologists, went from northern Mexico into the Tucson area, and from there into the Gila River Valley.

Casa Grande was abandoned around 1450. The original inhabitants left no written language behind. In his description of the large ancient structure before him, Padre Eusebio Francisco Kino wrote the words “casa grande”.

More became known about the ruins with the later visits of Lt. Col. Juan Bautistade Anza expedition in 1775 and Brig. General Stephen Watts Kearny’s military detachment in 1846.

Between the 1860’s and the 1880’s more people began to visit the ruins with the arrival of a railroad line twenty miles to the west, and a connecting stagecoach route that ran right by the Casa Grande. The resulting damage from souvenir scavenging, graffiti and outright vandalism raised serious concerns about the preservation of the Casa Grande.
