Pinaleno Mountains - GET #10, AZ

GET Segment 10 overview

The Pinaleños are a range defined by their considerable prominence. Rising to a height of nearly 11,000 feet above the sea, they are by a respectable margin the tallest of the true Southwestern Sky Islands. The range culminates atop Mount Graham, with a vertical relief of nearly 8000 feet the most prominent peak in the state of Arizona. According to the Nature Conservancy, the Pinaleños traverse five ecological communities and "contain the highest diversity of habitats in the shortest vertical distance of any mountain range in North America." Prickly pear and agave are at home here, only a few trail miles below an old growth forest of spruce and fir, the southernmost such forest on the continent.


In this segment our route traverses a portion of this remarkable range, often nicknamed simply "the Grahams." Using a combination of foot trails and pleasant forest roads, the GET follows the main northwest-southeast trending ridgeline, passing near scenic Riggs Lake, climbing forested Webb Peak (10,030'), and passing within range of the historic summer cabins at Old Columbine, before descending sharply along the range's dramatic east face toward the Gila Valley. The route bypasses the summit of Mount Graham itself, as the trails there are presently off-limits for the purpose of protecting one of the mountain's rare fauna, the Mount Graham red squirrel, found only here. For nearly two decades the mountain and its endangered red squirrels have been the subject of unlikely controversy between wildlife conservationists and the astronomical community, since the Pinaleños are also now home to the Mt Graham International Observatory, and indeed the dark, clear skies atop the range make this among the world's premier locations for stargazing. Nature and science appear to be coexisting for now, however harmoniously; hikers will note the telescope housing atop one of Mt Graham's sub-peaks from several vantages along the route.

In June and July of 2004, the lightning-caused Nuttall Complex fire burned some 30,000 acres of forest and brush, mostly on the Pinaleños' steep east-facing slopes. This fire and attendant erosion have caused considerable damage to the trail network as well as the ecology on this part of the range. Thankfully, Ash Creek Trail, which the GET uses here, received major trail rehabilitation in 2009 and 2010, resulting in a much improved hiking experience. (Forested Ash Creek Canyon was largely spared the direct effects of the fire, but not the subsequent flooding.) Still, several small burn areas and sections of vague or overgrown tread create ongoing challenges elsewhere in this segment; in addition to this guide description and the topo map set, plan to pack along an adventurous attitude - the rugged scenery here will reward those who are willing to persevere.

Spring season snowpack potentially poses another challenge. Snow on the Pinaleños often lingers above 9000 feet well into April, or later following an especially wet winter. As such, hikers at that time of year can expect to encounter at least some snowpack between milepoints 9 and 21 in this segment, and may want to remain open to the idea of detouring to avoid some or all of it. The primary concerns are the labor of postholing through saturated spring snow and the challenge of following snowbound trail, although slope exposure may also be of concern near Clark Peak, largely avoidable with care. Refer to the route details in the GET guidebook for more specific info, as well as the Snow Travel chapter of the GET Trek Planner.

NOTE: Hikers intending to traverse this entire segment may prefer to make use of the FR 286 Alternate in the segment's early miles. This alternate route avoids Johns Canyon Ridge Trail 313, which in places can be very difficult to follow due to ill-defined and overgrown trail.

A detailed, mile-by-mile description of this segment is available in the official GET guidebook. See www.GrandEnchantmentTrail.org

This segment of the GET forms part of a longer trip option between resupply locations, as described below:

GET Segments 6 - 11, Mammoth to Safford

East of AZ Hwy 77 the Grand Enchantment Trail heads into Sonoran desert foothills of the sky-island Galiuro Mountains, wherein lies the entrance to spectacular Aravaipa Canyon (BLM Wilderness). Sheer canyon walls rise a thousand feet above the lush, deciduous banks of perennial Aravaipa Creek, where we linger, wet feet and broad smiles, for some 12 unforgettable miles. Quiet dirt roads resume east of the canyon, leading within range of the remote outpost of Klondyke - another potential maildrop resupply location - before our route turns northeast to climb into the extreme rugged terrain of the Santa Teresa Wilderness (Coronado National Forest). Little-used trails provide supreme solitude as we navigate the adventurous granite-domed wonderland of Holdout Canyon, then over 7000-foot Cottonwood Mountain near well-named Pinnacle Ridge, and south to reach Klondyke Road. A fun yet challenging cross-country connection culminates at Tripp Canyon, where the GET soon rejoins foot trail to climb high into the forested Pinaleño Mountains (Coronado NF), passing serene Riggs Lake and the viewful fire tower atop 10,000-foot Webb Peak, where snow may linger well into spring. The desert heat seems as far away as the distant horizon atop this tallest of Arizona's Sky Island ranges, where broad panoramas reveal such distinguished neighbors as the Rincons, Huachucas, Chiricahuas, as well as the Mogollon Mountains in New Mexico farther along the GET. Leaving the high country by and by, we follow the magnificent craggy defile of forested Ash Creek Canyon on down toward the open desert nearly a vertical mile-and-a-half below, passing through an astonishing range of life zones in only a few miles of travel. Finally the route joins quiet greasewood-flanked dirt roads to reach the outskirts of bustling Safford, with most services available.
