Hi Fuller Canyon, AZ

Hi Fuller Canyon is flanked by Crackerbox Canyon, to its east, and East Miller Canyon, to its west. Of course.


Hiked north on FR 501A for a few hundred yards, before turning right into upper Hi Fuller Canyon. It starts wide, shallow, and mellow.

A mile north into the canyon, you will pick up a very old jeep trail. One end of the jeep trail heading up hill. According to the topo, it connects to FR 501 between Tracy Lynn Tank and FR 501B.

The jeep trail crosses the dry tank closest to Hi Fuller Spring, then turns southwest, uphill, where it must connect with FR 501A.

After stepping across a barb wire fence, Hi Fuller Canyon gets much tighter and deeper.

A quarter mile short of East Miller Canyon, there is a series of tall pours, with pools of unknown depth at the bottom. As with similar pours in other nearby canyons, the slope is concave, with overhangs. Higher speed individuals may try a direct route; I bypassed it.

There's a good sitting log at the junction of Hi Fuller Canyon and East Miller Canyon.

There are steep, but viable, routes west up to FR 320 and east up to FR 501, which you can walk back to the trailhead.

Or you can head back the way you came. Your choice.

The final section challenged me, but at 4.5 miles, it's low ROI for a 5-hour round trip from Phoenix. I'd only do this if I was already camping on the Rim.
