In the late '80's or early '90's I stumbled upon a pair of rock carvings in some granite boulders on state land east of my home. I have some slide photos of the carvings, but no location. After some noodling about in Google Earth, I went in search of them today. No luck, but I had fun trying. This area is rife with official and unofficial trails. The land is part of the study area for the McDowell Sonoran Preserve, though is unlikely to be added to the preserve. More is the pity for me living so nearby, yet I recognize the realities of the situation. City funds have been applied elsewhere, and for the better, because the land along Pima Road is some of the most expensive state land around. For this and other reasons I accept that this area will not likely be preserved.
Seems a good plan to wander the area over the next few years as time permits, it being so nearby. An Arizona state land recreational permit is required, and I happily keep mine up to date. And who knows? I may find those carvings again some day.
