  • Geologic Influences on Apache Trout Habitat in the White Mountains of Arizona
    GEOLOGIC INFLUENCES ON APACHE TROUT HABITAT IN THE WHITE MOUNTAINS OF ARIZONA JONATHAN W. LONG, ALVIN L. MEDINA, Rocky Mountain Research Station, U.S. Forest Service, 2500 S. Pine Knoll Dr, Flagstaff, AZ 86001; and AREGAI TECLE, Northern Arizona University, PO Box 15108, Flagstaff, AZ 86011 ABSTRACT Geologic variation has important influences on habitat quality for species of concern, but it can be difficult to evaluate due to subtle variations, complex terminology, and inadequate maps. To better understand habitat of the Apache trout (Onchorhynchus apache or O. gilae apache Miller), a threatened endemic species of the White Mountains of east- central Arizona, we reviewed existing geologic research to prepare composite geologic maps of the region at intermediate and fine scales. We projected these maps onto digital elevation models to visualize combinations of lithology and topog- raphy, or lithotopo types, in three-dimensions. Then we examined habitat studies of the Apache trout to evaluate how intermediate-scale geologic variation could influence habitat quality for the species. Analysis of data from six stream gages in the White Mountains indicates that base flows are sustained better in streams draining Mount Baldy. Felsic parent material and extensive epiclastic deposits account for greater abundance of gravels and boulders in Mount Baldy streams relative to those on adjacent mafic plateaus. Other important factors that are likely to differ between these lithotopo types include temperature, large woody debris, and water chemistry. Habitat analyses and conservation plans that do not account for geologic variation could mislead conservation efforts for the Apache trout by failing to recognize inherent differences in habitat quality and potential.

  • WEB GYMOAZ-07-20 Giants Among Us
    THE GIANTS AMONG US A Journey through the White Mountains BY ANNE GROEBNER When the Spanish and Hispanic explorers reached the southern section of Apache County, it is said that they “christened the expanse of snow-covered mountains before them ‘Sierra Blanca’ — White Mountains.” In his book, “A Sand County Almanac,” Aldo Leopold, one of Apache- Sitgreaves National Forest’s first forest assistants and a nationally, well regarded conservationist, refers to Mount Baldy as “White Mountain.” Possibly derived from a translation of the Apache’s name for it “Dził Łigai Sí’án" (“white mountain”). I write about this because there has always been the resounding question of whether it’s “White Mountains” or “White Mountain.” “Is there a White Mountain?” I am asked on many occasions…Regardless of its humble but wild beginnings, the stretch of landscape -- in an area we now affectionately call “The White Mountains” -- along Arizona Route 260, harbors some pretty amazing and gigantic hidden wonders. If you head south on AZ Route 260 toward Greer, the first town you come to after passing Hon- Dah Resort Casino is McNary. This town was once one of the largest logging towns in this area. It was named after James G. McNary, a banker from El Paso, who moved his logging business to the northeastern mountains of Arizona. The town of McNary, leased from the White Mountain Apache Tribe, was the center of everything in the White Mountains. Everyone came there for doctor visits because there wasn’t a hospital back then. They came there to bowl, to watch movies at Art Crozier’s movie theatre and to buy groceries.

  • GYMOAZ07-19 Mount Baldy
    Mount Baldy Wilderness: East Fork Trail from Gabaldon Campground I drove to the Gabaldon Campground, just south of the East Fork Trail of the Mount BaldyWilderness #95, to meet up with a Monday hiking group comprised of 11 hikers led by TRACKS member and trail guide George Tichenor. There is a connector trail from the campground and it is very convenient for horseback riders — each campsite has a corral. We weren’t riding horses but it was a great place to start after a 30+ minute drive from Pinetop because of the large parking area but most important -- its outhouse. We followed the connector trail through a meadow and then crossed the Little Colorado River just before connecting to the East Fork Trail. The Trail travels through meadows and tunnels and climbs through a forest of Colorado blue spruce, white fir, Douglas fir, Ponderosa pine, white pine and ancient aspen — Pines so tall and so wide, we couldn’t connect hands while trying to wrap our arms around the trunks. We hiked past giant boulders and spires that towered over the trail and continued hiking until we reached the rock cliffs. It was here that we stopped and feasted on watermelon that was trekked in by Ron Miller, avid hiker, climber of highest peaks and retiree from the BIA, then turned around and headed back. The hike back descends a gravel trail -- where I gracefully slid and fell (saving my camera) -- and Miller, who was hiking ahead of me, turned around and said “Oh, let me help you” as he tripped over an exposed root crossing the trail, nearly falling himself and then appropriately named it “the root of all evil.” I have to say that there is a sense of camaraderie on this trail (or any trail).

Copper Pamphlet produced by Tucson Chamber of Commerce, SAGU257, Box 1, Folder 11, WACC. “In a canon near the deserted mission of Cocospera, Cereus giganteus was first met with. The first specimen brought the whole party to a halt. Standing alone upon a rocky projection, it rose in a single unbranched column to the height of some thirty feet, and formed a sight which seemed almost worth the journey to behold. Advancing into the canon, specimens became more numerous, until at length the whole vegetation was, in places, made up of this and other Cacaceae. Description can convey no adequate idea of this singular vegetation, at once so grand and dreary. The Opuntia arborescens and Cereus Thurberi, which had before been regarded with wonder, now seemed insignificant in comparison with the giant Cactus which towered far above.” George Thurber, 1855, Boundary Commission Report.1 Table of Contents 1 Asa Gray, ―Plantae Novae Thurberianae: The Characters of Some New Genera and Species of Plants in a Collection Made by George Thurber, Esq., of the Late Mexican Boundary ii List of Illustrations v List of Maps ix Introduction Crowning the Queen of the Desert 1 The Question of Social Value and Intrinsically Valuable Landscapes Two Districts with a Shared History Chapter 1 Uncertain Pathways to a Saguaro National Monument, 1912-1933 9 Saguaros and the Sonoran Desert A Forest of Saguaros Discovering
