Peralta Canyon to Carney Springs Campground, Pinal County, AZ
There was a good water source about 2 miles in from Carney Springs, clear and fresh. The next water wasn't until right before the final saddle leading down into Siphon Draw and it was a small puddle to the side of the trail.
Note: There is a lot of climbing on this trail, even when you are going along the ridge line. There is a good camp spot behind the southern summit and another about a mile pass that. It can be very windy up here and there is NO cover.
