Round Valley

Pinto Mountain across Round Valley as seen from Black Canyon Road. The gray shrubs are Basin Sagebrush (Artemisia tridentata) and the large green shrubs are Utah Juniper (Juniperus osteosperma). Pinto Mountain is composed of Wild Horse Mesa Tuff, Winkler Formation, and Peach Springs Tuff. In the loose rock at the base of Pinto Mountain are boulders of gneiss and schist. That would indicate to me that the basement rock under Pinto Mountain is at or very near the surface.

Along Black Canyon Road, near Holliman Well, I collected Big Sagebrush, Yellow Rabbitbrush, and Purple Sage.

Black Canyon Road, looking north from near Gold Valley Ranch.

Black Canyon

View of Black Canyon Road, looking north from the vicinity of Gold Valley Ranch. The low gray shrubs are Blackbrush (Coleogyne ramosissima) and the large green shrubs are Utah Juniper (Juniperus osteosperma). This photograph was taken from a location about 50 meters north of the cows as seen in the photograph below. At first glance the vegetation might be classified as "pristine," as indeed much of the Mid Hills vegetation has been characterized. However, on closer examination there are many signs of usage by cattle, and it becomes impossible to know what the native vegetation might have been at this site.

Locations: Gold Valley Ranch.

Gold Valley Ranch

Cows along Black Canyon Road. The original vegetation at this location would have been dominated by Blackbrush (Coleogyne ramosissima) which can be seen in the background. However, heavy use by cattle, as they come to this location for water and salt, has completely destroyed the vegetation.

Locations: Table Top.
Table Top.

Table Top

The flat-topped mountain to the east of Black Canyon Road is Table Top. Geologic reports note that the Table Top is granite, topped by a quartz latite lava flow. The top surface is flat as it appears to be from the road. For most of its flat top, the vegetation consists of only two species, Basin Sagebrush (Artemisia tridentata) and Utah Juniper (Juniperus osteosperma).

Moat around rock on Table Top.

Small moats in the soils around rocks as shown in this photograph are common on Table Top. How the moats form is uncertain. However, it has been found that coarse particles will emerge from desert soils after as few as 4 wetting and drying cycles (Cook and Warren, 1973, p. 128). Once a rock like this emerges at the surface, continued rain runoff from the surface of the rock may wash the very fine particles away from the rock and cause a localized deflation around its edges.

Blackbrush along Black Canyon Road in Gold Valley

Blackbrush Scrub along Black Canyon Road. This view looks northwest toward Gold Valley Mine and the Little Thorn Mountains. The dark gray shrubs are Blackbrush (Coleogyne ramosissima). This is one location in the Eastern Mojave where Blcakbrush reaches its maximum dominance. Relative density of Blackbrush is about 70% at this location.

Vegetation near Hole-in-the-Wall.

General view of the vegetation approximately 1 km southeast of Hole-in-the-Wall. As you can see, this picture was taken in an unusually green Spring. The cactus in the foreground is Buckhorn Cholla (Opuntia acanthocarpa). The large tree-like plants are Mohave Yucca (Yucca schidigera). The smaller shrubs are boxthorns (Lycium sp.), Blackbrush (Coleogyne ramosissima), and Great Basin Blue Sage (Salvia dorrii).
