In a hundred years from building the Casa Grande, the people disappeared.

With all the effort to build such a HUGE structure in about 1350 AD why did the Sonoran Desert people disappear about a hundred year after the building of this Casa Grande. There is archeological evidence to indicate that about 1450 the people "disappeared" from the area. My suggestion is the Bubonic plague that devastated Europe and Asia to the tune of killing almost 200 million people. February 5th, 2023 Arizona desert south of Phoenix mefoundation.world
