You have to go into the mountains around Tucson to climb public trees. I chose to go into the Santa Catalina Mtns in the Coronado National Forest. Along the highway they have a bunch of pulloffs for scenic viewing. I found a stand of sycamore trees in a dry riverbed next to the road. I had to climb down the side of the road about 50' to get to the riverbed, but it wasn't too bad. I climbed a sycamore that seemed to have the least amount of lean (the one furthest to the right in the picture below). Second picture was taken when I was in the tree at about 50'. It's a view of the canyon I was in.
Until I was in the tree, I had forgotten about the
discussion
of the white powder on sycamores. Although there was a lot of dust, it didn't bother me. I did take a shower as soon as I could, though.
I didn't spend quite as much time in the tree as I would have liked, but the canyon was starting to get dark and I didn't feel like making a mistake while I was alone in a new area. I had a headlight and a phone, but why take chances? Overall, a great climb in a great area.
