This place has an interesting history. It's in Mesa Arizona outside of Phoenix. In it's day it was a hot springs resort. There's a quirky YouTuber named Wonderhussy that goes to different locations and gives the history of them. She lives near Death Valley and travels mostly Nevada, California and other western states. She did a thing on this former resort about a week ago. Disclaimer: I have no connection or interest in her or her "channel" other than I find her entertaining a couple of times a week for about 30 minutes or so at a time.
