We did this hike as a near-trifecta of Upper Tonto Basin ruins that included Black Mountain Ruins and an attempt at the Gisela Ruins.
Very easy hike with a trailhead accessible to smaller vehicles as it's less than 1/2 mile from the highway. Lots of parking next to the old corral.
The hike up the hill is easy. Just be on the lookout for fresh cow patties. The rock wall is unique, but there is evidence of recent diggings up there. We also found pottery shards along the slope. Nice views of the Sierra Anchas, the Tonto Basin and the famous Jake's Corner Bar.
On the way back we went to investigate Mud Spring but it has indeed been diverted to provide water for the stock tank inside the corral.

A campfire must be extinguished by drowning it with water, stirring with a shovel, and repeating that process until the campfire is cold to the touch. A campfire is still a danger if it has any trace of heat, and must not be left or abandoned. Wildfires can begin by abandoned campfires that rebuild heat on windy days and then blowing embers ignite surrounding grasses and brush.
