Casa Grande National Park, or Big House in English, is the large ruins of the vanished Hohokam Indian tribe. They used the materials of the desert, saguero cactus ribs, mud, and juniper trees in their construction.
And deer were common delicacies. Brian can tell you more about deer antlers seeings how he's dealt with them previously this year.
Sophie had previously been to Casa Grande when she was 3 months old. Now at almost the age of 5, she got to take her little brother (age 1) and show him around. When we told her she'd been her before, she answered: "Yeah I know. I remembered." We got a good laugh out of it.
The main house is 4 stories made of 3,000 tons of caliche (mixture of sand, clay, limestone) plastered over saguaro ribs and wood from juniper, pine, and fir trees. The four walls align with the four compass points and some of the circular holes in the building align with the setting sun and moon during specific times.
Other than Casa Grande there were other areas or "rooms" that were once buildings within the Casa Grande complex.
Some storage, others small homes, and another which was a larger home of one of the more wealthy citizens of the Indian tribe.
