We scrambled up this route in the rain and fog. The petroglyphs are very nice. We did 26 other peaks on this 21 day road trip. See the trip report with photos for more information.
I climbed Superstition Peak yesterday from Carney Spring TH, and then went on about 2 miles farther towards Flatiron. Today I wanted to hike up to meet that trail but got a late start so wasn't sure I would make it. I left the TH at 2:35 and reached the saddle in just under 2 hours. After looking around awhile up there and taking pics, I was back down at the TH at 6:25, getting some nice sunset pics just before that. Lots of people up to the Petroglyphs, met about 6 people above that.
Pretty straight forward route, some minor route finding needed. The page makes it seem like just a quick walk up once you gain the ridge (minus the little class 3 stated) but your less than half way when you hit the "hanging rock" and the ridge. We climbed pretty quickly and it took us 5 1/2 hours.
