Bull Pasture Trail / Mount Ajo Day Hike

(part of the Organ Pipe Cactus National
Monument Car Camp
, March 12-14)

when? Saturday, March 13, 2004
where? Organ Pipe Cactus National Monument
the hike A round-trip day hike in the Organ Pipe Cactus National Monument Wilderness Area. The trail to Bull Pasture is a fine day loop that features the rugged western wall of the Ajo Mountains. The maintained trail climbs to a ridge overlooking Bull Pasture, a scenic basin high on the flanks of the Ajo range. Bull Pasture was a favorite cow pasture back in the days when grazing was still allowed in the area. The trail continues to the peak of Mount Ajo, though it is much less used past the Bull Pasture overlook. Depending on conditions, some may wish to continue on the peak. Either way, the return part of the loop is on the Estes Canyon Trail.
