I’m trying to visit a few National Park sites I haven’t seen before on my way to Texas. Even though I live in Arizona there are So many parks I haven’t been to yet and one of them was Casa Grande Ruins National Monument.
I’ve seen a few Southwest native ruins but nothing built like the “Great House” at Casa Grande National Monument. Almost 1000 years ago the Hohokam people constructed this four story 60 foot long building using subsoil called caliche, a concrete-like mix of sand, clay and calcium carbonate.
Imagine the labor involved piling 3,000 tons of caliche mud in successive courses to form walls four feet thick at the base and tapering toward the top. Juniper, pine and fir trees used to form ceiling or floors were carried or floated 60 miles down the Gila River.
The walls face the four cardinal points of the compass and a circular hole in the upper west wall aligns with the setting sun at the summer solstice. Other openings also align with specific solar and lunar occurrences. The sky was their calendar.
And the Great House is only part of this 2-acre compound surrounded by what was once a 7 foot high wall that contained houses, work areas, courtyards and storage rooms. Plus this is only one neighborhood in a larger community of compounds that covered nearly a square mile housing possibly 30,000 to 60,000 people. The Hohokam were farmers that built the most extensive irrigation ditches lined with caliche from the Gila River and had a lot of mouths to feed.
When Americans began visiting the area in the late 1800s souvenir hunting threatened to destroy the site. In 1892, Casa Grande became the first archaeological reserve and declared a National Monument in 1918. The Great House has been sheltered since early excavations started in 1903.
How did I learn all this? Well of course, I became a Junior Ranger.
What a great post. I love hearing about the history of other countries especially where there are ruins and such like. It is all so different to the Roman remains which we mostly find in Europe other than way back to the stone age. Very interesting. Thanks Gaelyn. Drive carefully, Diane
This is a fantastic structure. I wonder how many others melted away in the tears of time? And the people vanished into other nations..,
A super post, Gaelyn. Thanks for sharing.
Gaelyn, Your post on the Great House is wonderful. I never realized the Hohokam people built such a massive astrological observatory. Thanks for the history lesson!
This is a fascinating spot! It's hard to imagine so many people living in such a small area in that place and time. It's also strange how we will travel great distances to see the sights in other parts of the world and not take the time to visit those in close proximity to us. I'm glad you are making time to do that. You make a good Jr. Ranger!
I had never heard of this park, but it looks fascinating. I love visiting old ruins and imagining what life might have been like for the people who lived there.
Great photos!
