Trail Route Description:  This passage begins at a gate just north of the Tonto National Forest boundary about 0.4 miles due west of Ajax Peak. From here the trail climbs briefly and then drops down into a drainage about 1 mile in. After crossing this drainage it climbs up to the high point for this passage at 3,780 feet. It then begins a gradual descent over roughly 2.3 miles until it arrives at FR 4.
After crossing FR 4 the trail continues west and turns north, contouring around several small drainages. At just over 8 miles from the beginning the trail makes a hard turn to the west and begins working its way around Picketpost Mountain. The trail wraps around to the west side of Picketpost and somewhat parallels the Alamo Canyon drainage. After crossing Alamo Canyon it reaches the end of the passage at the Picketpost Trailhead.

Difficulty:  Moderate
