Soilscape along Hwy 64 in the area north of Williams, Arizona
The soils in the foreground are dominantly in the Winona series. The Winona series consists of very shallow and shallow, well drained soils that formed in eolian deposits over alluvium from limestone and calcareous sandstone. Winona soils are on plateaus and hills and have slopes of 0 to 70 percent. The mean annual precipitation is about 11 inches and the mean annual air temperature is about 52 degrees F.
TAXONOMIC CLASS: Loamy-skeletal, carbonatic, mesic Lithic Ustic Haplocalcids
USE AND VEGETATION: These soils are used for livestock grazing and wildlife habitat. Vegetation is blue grama, black grama, needleandthread, galleta, sand and spike dropseed, hairy grama, muttongrass, bottlebrush, squirreltail, alkali sacaton, winterfat, bigelow sage, fourwing saltbush, cliffrose, juniper and pinyon pine.
DISTRIBUTION AND EXTENT: Northern Arizona and west central New Mexico.

Soils in the mid-ground are typically Lithic Ustic Torriorthents. Lithic Ustic Torriorthents have more available moisture than Lithic Torriorthents during summer or, if located in the Tropics, during the rainy seasons. They are moist in some or all parts of the moisture control section for more than one-fourth of the time (cumulative) when the soil temperature at a depth of 50 cm exceeds 5 oC. They have a shallow or very shallow lithic contact, which limits the moisture-storage capacity. Consequently, the soils commonly are associated with the Ustalfs and Ustolls on more stable surfaces. Lithic Ustic Torriorthents are of moderate extent in the United States. They are used mostly for winter or spring grazing.
Torriorthents are the dry Orthents of cool to hot, arid regions. They have an aridic (or torric) moisture regime and a temperature regime warmer than cryic. Generally, they are neutral or calcareous and are on moderate to very steep slopes. A few are on gentle slopes. Many of the gently sloping soils are on rock pediments, are very shallow, have a sandy-skeletal particle-size class, or are salty. Others are on fans where sediments are recent but have little organic carbon. The vegetation on Torriorthents commonly is sparse and consists mostly of xerophytic shrubs and ephemeral grasses and forbs. They are extensive in the Western United States.

In the background is Humphreys Peak, the highest point in Arizona at 12,633 feet and one of the most scenic viewpoints in the San Francisco Peaks. On clear days hikers can see the Grand Canyon from the summit. The alpine forest trail is located just north of Flagstaff. This is a strenuous rocky trail with over 3,000 feet elevation gain. Humphreys Trail is open year round but snow can make the hike difficult during the winter months. Humphrey's Peak is a 9.2 mile moderately trafficked out and back trail located near Flagstaff, Arizona that features beautiful wild flowers and is only recommended for very experienced adventurers. The trail offers a number of activity options and is accessible year-round.
