The Alabama Hills are a range of hills and rock formations near the eastern slope of the Sierra Nevada in the Owens Valley, west of Lone Pine in Inyo County, California.

Though geographically separate from the Sierra Nevada, they are part of the same geological formation. The rounded contours of the Alabamas contrast with the sharp ridges of the Sierra Nevada to the west. Though this might suggest that they formed from a different orogeny, the Alabamas are the same age as the Sierra Nevada. The difference in wear can be accounted for by different patterns of erosion.

Dozens of natural arches are among the main attractions at the Alabama Hills. They can be accessed by short hikes from the Whitney Portal Road, the Movie Flat Road and the Horseshoe Meadows Road. Among the notable features of the area are: Mobius Arch, Lathe Arch, the Eye of Alabama and Whitney Portal Arch.

The Alabama Hills were named for the CSS Alabama, a Confederate warship deployed during the American Civil War. When news of the ship’s exploits reached prospectors in California sympathetic to the Confederates, they named many mining claims after the ship, and the name came to be applied to the entire range. When the Alabama was finally sunk off the coast of Normandy by the USS Kearsarge in 1864, prospectors sympathetic to the North named a mining district, a mountain pass, a mountain peak, and a town after the Kearsarge.

The Alabama Hills are a popular filming location for television and movie productions, especially Westerns set in an archetypical “rugged” environment. Since the early 1920s, 150 movies and about a dozen television shows have been filmed here, including Tom Mix films, Hopalong Cassidy films, The Gene Autry Show, The Lone Ranger and Bonanza. Meanwhile, Classics such as Gunga Din, The Walking Hills, Yellow Sky, Springfield Rifle, The Violent Men, Bad Day at Black Rock (1955), the Budd Boetticher/Randolph Scott “Ranown” westerns, part of How the West Was Won, and Joe Kidd. In the late 1940s and early 50s the area was also a popular location for the films of B-western actor Tim Holt.

10-30-20 – Little Finland at Gold Butte National Monument

Little Finland (also known as Hobgoblin’s Playground and Devil’s Fire) is a scenic red rock area, located in a remote section of Clark County, Nevada south of Mesquite, known for its red rock scenery and strangely-shaped, delicate rock formations. The landscape is similar to Valley of Fire State Park, which is about 20 miles (32 km) to the west, across Lake Mead. The rock formations are composed of red Aztec Sandstone, fossil sand dunes. Many of the features are small erosional fins, hence the name.

Little Finland is accessible via the BLM Gold Butte Backcountry Byway, which also goes through the historic mining town of Gold Butte, Nevada, established in 1908. Other nearby attractions include Whitney Pockets, another scenic red rock area with petroglyphs, and the Devils Throat, a sinkhole. The Gold Butte region is public land managed by the Bureau of Land Management that contains seven BLM-designated Areas of Critical Environmental Concern (ACEC). Since December 2016, Little Finland and the surrounding area have additional federal protection within Gold Butte National Monument.

Two BLM wilderness areas are nearby. The Lime Canyon Wilderness borders Little Finland and the west side of the Gold Butte Byway loop. The Jumbo Springs Wilderness is south of the Gold Butte townsite.

Rainbow Basin is a geological formation in the Calico Peaks range, located approximately 8 miles (13 km) north of Barstow in the Mojave Desert in San Bernardino County, California.

The Rainbow Basin has been designated a National Natural Landmark and is in the Bureau of Land Management managed Rainbow Basin Natural Area. Rainbow Basin is a mixture of private and public land, but it is managed by the Bureau of Land Management. It is accessible to the public via Irwin Road from Barstow to an unpaved loop road through the colorful basin.

The basin is notable for: the fantastic and beautiful shapes of its rock formations: its fossil beds, which have provided scientists with valuable information about life during the middle Miocene epoch, between 12 and 16 million years ago; and to the northeast the Calico Early Man Site.

Underneath Rainbow Basin is the massive batholith that lies below much of the western Mojave. Made from a type of rock called quartz monzonite, this batholith dates to either the Cretaceous, or possibly the late Jurassic period. Early in the Cenozoic Era this batholith was exposed in the area surrounding Rainbow Basin and bent downward as it underwent compression, to form a basin. Sediments deposited in this basin became the sedimentary rocks that are most visible in Rainbow Basin today. Further compression, uplift, and finally extension left these sedimentary formations deeply folded, the most prominent fold being the Barstow Syncline. These same stresses also produced several faults in the Rainbow Basin area.

The thick sedimentary layers can be divided into three distinct formations. The lowest is called the Jackhammer Formation, and it is composed of layers of sandstone, siltstone, limestone, and conglomerate, all probably dating to the early Miocene Epoch.

Above this is the Pickhandle Formation. The sediments making up this formation are mostly of volcanic origin – tuff, rhyolite and andesite, indicating that they were laid down during a period of active volcanism. That time was probably during the early Miocene.

The highest of the three formations is the Barstow Formation, which is made up of layers of conglomerate, limestone, sandstone, and shale. This formation dates to the middle to late Miocene and it contains one of the largest Cenozoic fossil assemblages in North America. Most of the sediment that makes up the layers in this formation was stream-laid, but there is a white layer of rhyolitic tuff (sometimes called marker tuff) near the top.

Finally, on top of everything else, is a relatively thin layer of fanglomerate (alluvial fan deposits) laid down during the late Pleistocene. Differential erosion of rocks of different hardness finished the job of sculpting the formations into the fantastic shapes that can be seen in Rainbow Basin today.

03-08-20 – Gold Butte National Monument

Gold Butte National Monument is a United States national monument located in Clark County, Nevada, northeast of Las Vegas and south of Mesquite and Bunkerville. The monument protects nearly 300,000 acres of desert landscapes featuring a wide array of natural and cultural resources, including rock art, sandstone towers, and important wildlife habitat for species including the Mojave Desert tortoise (a threatened species), bighorn sheep, and mountain lion. The area also protects historic ranching and mining sites such as the ghost town of Gold Butte, although little but mine openings, cement foundations, and a few pieces of rusting equipment remains. The monument is managed by the Bureau of Land Management.

The monument consists of 296,937 acres (120,166 ha). The Gold Butte National Monument fills a gap between Lake Mead National Recreation Area and Grand Canyon-Parashant National Monument, creating a continuous swath of conserved land and establishing a wildlife corridor. Significant wildlife within the borders of the park include Mojave Desert tortoise (a threatened species), bighorn sheep, and mountain lion, as well as Gambel’s quail and chukar partridge. Important cultural and natural resources within the monument include rock art and sandstone formations. Within the park, “weather-chiseled red sandstone is incised with ancient rock art, and the remains of rock shelters and hearths, agave roasting pits and projectile points” may be found.
