Picacho

Picacho covers 4,969 acres along the south rim of the Salt River canyon on the Tonto National Forest's Globe Ranger District, in Coconino, Gila, Maricopa, and Navajo counties, Arizona. The terrain is mountainous and montane, anchored by Picacho Colorado, the Salt River Canyon, and the inlet drainages of Rock Canyon, Walnut Canyon, Regal Canyon, and Coyote Canyon as they fall toward the Salt River Valley and Salt River Draw. The watershed is rated as major in hydrological significance: the Rock Canyon–Salt River headwaters feed the Salt River, with Canyon Creek, Ash Creek, and Cibecue Creek entering nearby. Cedar Spring, Mormon Spring, and Lower Fourth of July Spring hold water in the upland drainages, supplemented by Ash Spring Tank and Cypress Pasture Tank.

Vegetation stacks across a steep elevation transition from the river corridor to the upland rim. Along the Salt River and the perennial reaches of its tributaries, Warm Desert Streamside Mesquite Grove holds Wright's sycamore (Platanus wrightii), willowleaf false willow (Baccharis salicifolia), and southern maidenhair fern (Adiantum capillus-veneris) in damp pockets, with crimson monkeyflower (Erythranthe verbenacea) at the wet edges. Above the river, Saguaro Cactus and Palo Verde Desert and Upper Sonoran Desert Scrub carry saguaro (Carnegiea gigantea), ocotillo (Fouquieria splendens), jojoba (Simmondsia chinensis), and spoonflower (Dasylirion wheeleri). Mojave Creosote Desert and Apache-Chihuahuan Desert Grassland open the broader basin. The rim and upper benches rise into Arizona Plateau Chaparral, Sky Island Pinyon-Juniper Woodland, Sky Island Juniper Savanna, Sky Island Oak Woodland, and Sky Island Pine-Oak Forest; isolated Southern Rockies Ponderosa Pine Woodland patches occur on the coolest slopes.

Wildlife uses every layer. In the streamside woodland, common black hawk (Buteogallus anthracinus) hunts over pools, while Bell's vireo (Vireo bellii), yellow-breasted chat (Icteria virens), and black phoebe (Sayornis nigricans) work the willow and sycamore canopy. Razorback sucker (Xyrauchen texanus) and Gila topminnow (Poeciliopsis occidentalis) occupy the Salt River and its tributary pools; canyon treefrog (Dryophytes arenicolor) calls from rock pools at night. On the desert slopes, Gila woodpecker (Melanerpes uropygialis) and Scott's oriole (Icterus parisorum) nest in saguaro and yucca; western diamond-backed rattlesnake (Crotalus atrox) and Sonoran whipsnake (Masticophis bilineatus) hunt insects and lizards. The canyon walls hide ringtail (Bassariscus astutus) and white-nosed coati (Nasua narica); Arizona gray squirrel (Sciurus arizonensis) and American black bear (Ursus americanus) move between oak woodland and streamside cover. Wapiti (Cervus canadensis), white-tailed deer (Odocoileus virginianus), and cougar (Puma concolor) range the upper rim, where pinyon jay (Gymnorhinus cyanocephalus) caches seeds in the juniper canopy. Portions of this area fall within the potential range of several federally listed species; see the Conservation section for details.

Dropping off the Salt River canyon rim, a visitor descends through pinyon-juniper and chaparral onto saguaro-palo verde slopes, then into shaded reaches of Rock Canyon or Walnut Canyon where the air cools and cottonwood and sycamore canopy closes overhead. The Salt River runs below in basalt and limestone walls; canyon treefrogs call from pools at dusk. Climbing back to Picacho Colorado, the view opens west across the river toward the San Carlos Apache Reservation and the broader Tonto landscape.

Picacho is a 4,969-acre Inventoried Roadless Area in the Tonto National Forest, in Coconino, Gila, Maricopa, and Navajo counties, Arizona. The area is managed within the Globe Ranger District and lies in the U.S. Forest Service's Southwestern Region, draining the Rock Canyon–Salt River headwaters into the Salt River. The area is protected under the 2001 Roadless Area Conservation Rule.

The Yavapai and the Western Apaches lived similar ways of life as nomadic hunters and gatherers, but they represented completely different linguistic groups [1]. Both the Yavapai and Western Apaches lived in Tonto Basin [1]. The rim of the Salt River Canyon contains a number of prehistoric hilltop compounds that served as year-round habitation sites but were also defensive in character [5].

In 1863, gold was found in the drainages of the Bradshaw Mountains at Turkey Creek and months later at Lynx Lake near Prescott [4]. Camp Reno near Tonto Creek was established in 1867, and Fort Apache was built on the headwaters of the Salt River in 1870 [1]. The U.S. Army under General George Crook initiated the Tonto War in November 1872 [1]. On February 27, 1875, 1,476 Yavapai and Apache people were force-marched as prisoners of war for 180 miles from the 1871 Camp Verde Reservation to the San Carlos Apache Reservation [4]. Of the roughly 1,450 Apaches and Yavapais who began the journey, at least 100 died along the way [1]. After Geronimo surrendered in September 1886, the Army began issuing permits so Yavapai and Apache people could work off the reservation in Globe, Arizona, cutting "grass hay" for the Army and gathering traditional food to supplement government rations [4]. In 1972, 97 years after the Exodus, the Tonto Apache Reservation—only 85 acres, the smallest in Arizona—was created on Tonto National Forest land near Payson [1].

The private property at Chrysotile, on the south rim of the Salt River canyon near the Picacho roadless area, was at one time one of the largest asbestos mines in Arizona [5]. The Globe area at the southern edge of the area drew Yavapai and Apache workers in the late 19th century and remained a mining and ranching center into the 20th [4].

President Theodore Roosevelt established the Tonto Forest Reserve by Proclamation 598 on October 3, 1905, reserving lands in the Territory of Arizona that were in part covered with timber for the public good [2]. The Tonto National Forest now spans 2.9 million acres of rugged Arizona, with landscapes from Sonoran Desert saguaro to the highlands of the Mogollon Rim [3]. Picacho lies in the extreme east-central part of the Tonto National Forest on the Globe Ranger District, bounded on the east by San Carlos tribal lands and on the north and west by the Salt River [5]. The roadless designation preserves a section of the Salt River canyon system between San Carlos lands and the broader Tonto landscape.

Vital Resources Protected

• Salt River Canyon Watershed Protection: Picacho's 4,969 roadless acres include the Rock Canyon–Salt River headwaters, with Walnut, Regal, and Coyote canyons draining steeply into the Salt River through Picacho Colorado. The watershed carries a major hydrological significance rating. Keeping the canyon walls and rims uncut allows precipitation to enter the soil rather than running directly off bare surfaces, supplying cool baseflow to the Salt River and supporting downstream habitat for native fish, including razorback sucker (Xyrauchen texanus), which has designated critical habitat in the Salt River system.

• Riparian Function in Salt River Streamside Mesquite Grove: Warm Desert Streamside Mesquite Grove with Wright's sycamore (Platanus wrightii), willowleaf false willow (Baccharis salicifolia), and southern maidenhair fern (Adiantum capillus-veneris) lines the Salt River and its perennial tributaries. The intact upland slopes around the canyon dampen flood pulses and sustain pool habitat through the dry season. This streamside woodland shades the river, traps sediment from upslope runoff, and provides nesting and foraging habitat for common black hawk (Buteogallus anthracinus), Bell's vireo (Vireo bellii), and yellow-breasted chat (Icteria virens).

• Connectivity Between San Carlos Lands and Tonto Uplands: Picacho lies between San Carlos tribal lands on the east and the broader Tonto National Forest landscape on the west, with Sky Island Pinyon-Juniper Woodland covering more than 60 percent of the area and Sky Island Oak Woodland and Pine-Oak Forest on the cooler benches. The roadless condition keeps this canopy continuous, allowing cougar (Puma concolor), American black bear (Ursus americanus), wapiti (Cervus canadensis), and white-tailed deer (Odocoileus virginianus) to move between reservation lands and the Salt River corridor without crossing a road network.

Potential Effects of Road Construction

• Sedimentation into the Salt River and Native Fish Habitat: Road construction across the steep cliffs that drop into Walnut, Regal, and Rock canyons would expose mineral soil on cut and fill faces. Surface runoff would deliver fine sediment directly into the Salt River, filling interstitial gravels and pool habitat that razorback sucker, Gila topminnow (Poeciliopsis occidentalis), and southwestern willow flycatcher (Empidonax traillii extimus) habitat depend on. Cut slopes shed material for years after construction, producing chronic rather than one-time sediment loading.

• Fragmentation of Pinyon-Juniper and Saguaro-Palo Verde Canopy: A road corridor cut across the area would slice through Sky Island Pinyon-Juniper Woodland and Saguaro Cactus and Palo Verde Desert in continuous canopy. NatureServe assessments identify roads as a pervasive threat to wide-ranging species in this region, including Mexican wolf (Canis lupus baileyi), black bear, cougar, and ringtail (Bassariscus astutus). Restoring connectivity once severed requires the long process of re-vegetating cut slopes and re-establishing crossings across a hard linear feature.

• Invasive Annual Grasses in Saguaro-Palo Verde and Creosote Desert: Construction equipment and the bare, disturbed surface of a new road act as a vector and seedbed for non-native annual grasses such as buffelgrass (Pennisetum ciliare). Once established in Saguaro Cactus and Palo Verde Desert and Mojave Creosote Desert, these grasses increase fine-fuel loads and carry fast-moving fires through saguaro stands that are not adapted to repeated burning. The combination is difficult to reverse because each disturbance reseeds the invasive community and each subsequent fire favors more grass over native saguaro and palo verde.

Picacho covers 4,969 acres along the south rim of the Salt River canyon on the Tonto National Forest's Globe Ranger District, in Coconino, Gila, Maricopa, and Navajo counties. The area contains no maintained trails, no designated trailheads, and no developed campgrounds. Recreation is dispersed and unguided. Access requires a foot descent from the Salt River canyon rim, with the area bounded by San Carlos tribal lands on the east and the Salt River on the north and west. Visitors should expect rugged ground, loose rock on the cliffs, narrow drainages in Walnut, Regal, and Coyote canyons, and a sharp elevation transition from saguaro at river level to pinyon-juniper on the rim.

Hunting in and around Picacho follows Arizona Game and Fish Department regulations for the units that include the Salt River canyon and the Tonto National Forest. The mosaic of pinyon-juniper, chaparral, oak woodland, saguaro-palo verde, and desert grassland supports general hunts; wapiti (Cervus canadensis) and white-tailed deer (Odocoileus virginianus) range the upper rim, American black bear (Ursus americanus), mountain lion (Puma concolor), and wild turkey (Meleagris gallopavo) use the canyons, and desert cottontail (Sylvilagus audubonii) occurs across the desert slopes. Hunters should verify current AZGFD seasons and unit boundaries before entering, and recognize that the eastern boundary abuts tribal land.

Birding documentation around Picacho is sparse but high-quality. Three eBird hotspots fall within 24 km of the area: Seneca Lake Recreation Area on the San Carlos Apache Reservation (179 species, 74 checklists — permit required from San Carlos), Salt River Canyon (125 species, 165 checklists), and Timber Camp Campground (114 species, 219 checklists). Within Picacho itself, common black hawk (Buteogallus anthracinus) hunts over the Salt River pools; Bell's vireo (Vireo bellii), yellow-breasted chat (Icteria virens), and black phoebe (Sayornis nigricans) work the streamside willow and sycamore canopy; Gila woodpecker (Melanerpes uropygialis) and northern cardinal (Cardinalis cardinalis) hold in the saguaro slopes.

The Salt River along the area's north and west boundary is the primary water-based recreation route in the region. Float trips on the Upper Salt River pass below the Picacho rim, providing access to side canyons such as Walnut and Regal that drop into the river. Flathead catfish (Pylodictis olivaris) occurs in the Salt River; angling is governed by Arizona Game and Fish regulations, and reaches on the reservation side require a San Carlos tribal permit. Canyon treefrog (Dryophytes arenicolor) calls from pools at dusk.

Because there are no Forest roads inside Picacho, every activity—the descent from the rim into Rock or Walnut Canyon, a river-trip side hike into the area, hunting the upper benches, photographing saguaro against canyon walls—depends on a foot approach across continuous, undisturbed terrain. A road corridor would shorten the walk-in but would fragment the elevational gradient from saguaro to pinyon-juniper, deliver sediment and noise to the Salt River corridor, and remove the backcountry character that distinguishes Picacho from the more accessible parts of the Tonto National Forest.
