Went looking for the Monroy Ranch this past week.  It was one of the landmarks on the early 1900's topo map I found online.  I found the old Arizona Dam site the week before last.  The top map showed the ranch  SE of what is now the Ellsworth - Bush Hwy intersection in the Salt River Recreation Area.  I looked around that area on Thursday but didn't find any sign of ranching like old fencing, corrals or foundations.

Today, I walked around SW of the same intersection.  While I still didn't see much in the way of direct physical signs of ranching,  much of the are seemed to have been overgrazed.  It was very pretty with the new grass but the plants were much less dense than in neighboring areas.  There were also several old roads crossing the area.  It would be my guess that the area was part of a ranch at some time.
