Top view is straight to Piestewa but what I was focused on as well was the dam. Bottom photo shows what caught my eye. The big earthen dam behind the dam structures.

Cave Creek Dam was built to protect Phoenix from flash floods in the big Cave Creek Wash. It was replaced later with the Cave Buttes Dam. I found this cool photo of some flooding at the dam from back in the day: https://www.azcentral.com/story/travel/ ... /13513403/

The dam was modified in 2020. To alleviate the water pressure build-up as stormwater accumulates behind the earthen dam, the Flood Control District of Maricopa County decided to build an additional 61” outflow structure.
