If you're convinced the Flatiron is the toughest out-n-back hike in the valley, this one might change your mind.
The Flatiron is more equivalent to 2 Squaw Peak or Camelback acsents. This bad boy is closer to 3 or a Humphries ascent.
The original survey done on Peak 5057 is one of oldest surveys done in Arizona (1899). Those original surveyors hiked up there with pack mules. I can't even imagine doing that hike with pack mules, especially going up Carney Springs. Obviously, we can only assume there was basically no trail for them to follow in 1899. They left the mules below the peak while they did their survey work.
In subsequent years, (1910, 1936, 1938, and 1946) other surveyors put the various present 3 survey disks up there (& one carving in a boulder). The main disk is the one with the triangle on it, and the other 2 disks (Reference Marks) have arrows on them, pointing to the triangulation disk. The surveyors also carved that rudimentary "arrow" in a nearby boulder, pointing to the main disk. That carving was done in 1910, and also acted as a Reference Mark.
Next time you are up there, see if you can locate all 3 disks (easy) and the tiny arrow carving in the boulder. (not so easy)
