Scenic Nevada spots were discovering

There are few experiences as rewarding as venturing into the vast Nevada landscape to discover a place that hardly anyone has ever visited.

Out beyond the cities and towns are dozens of natural areas boasting unique geological features, rare plants and animals, and other intriguing qualities that are worth trying to find, including the following:

Lexington Arch, Great Basin National Park—Great Basin National Park has so many extraordinary features such as, Lehman Caves, Wheeler Peak, ancient bristlecone pines, and a glacier, that Lexington Arch, located near the park’s southeastern boundary, often is overlooked. It shouldn’t be.

Lexington Arch is an impressive, 75-foot-high limestone bridge. The arch is considered unusual because most other arches in the West are carved from sandstone.

Experts suggest that Lexington Arch may once have been part of a cave, the rest of the rock having worn away. They point to the presence at its base of flowstone, a smooth rock usually found in caves.

Other geologists theorize that the arch is a natural bridge carved by the waters of Lexington Creek. Long ago, when the walls of Lexington Canyon were not so steep, the creek may have flowed through a cave in the wall of the canyon and, over time, eroded the tunnel into a large arch.

Regardless of its origins, Lexington Arch is an imposing landmark that, despite its obvious attributes, is one of the least-known places in Great Basin National Park.

One reason for the lack of visitors is its remote location. To reach the arch from the park’s visitor center, drive east to Baker for five miles and turn right on Nevada State Route 487. Drive south 10.7 miles (you’ll pass into Utah, then back into Nevada).

Continue through Garrison, Utah, to Pruess Lake. Take the first dirt road on the right just south of Pruess Lake. Proceed 12 miles on the dirt road (there will be signs leading to the arch) to a small parking area. A moderately steep hiking trail leads 1.7 miles to Lexington Arch.

White Domes, Valley of Fire State Park—While the Valley of Fire is pretty well known, the White Domes Area is one of the state park’s least visited spots. Located at the north end of the park, which is 50 miles northeast of Las Vegas, White Domes is a field of white sandstone ridges, slot canyons, and outcroppings that don’t appear to be of this world.

With white-chocolate-smooth rock faces and stone ripples, White Domes seems to have been poured into place rather than forged by geological forces. This part of Nevada sat beneath an inland sea until about 150 million years ago. Over time, thick layers of mud and sand on the lake’s bottom were transformed into limestone and sandstone, which, eventually were sculpted into interesting shapes by rain and wind.

The park’s distinctive red sandstone is the result of oxidized iron that permeated the rock. At White Domes, however, the iron has leached out in places, producing white sandstone that starkly contrasts with the surrounding red rock.

Traveling on the gravel White Domes Road, an 11-mile roundtrip from the park’s visitor center, you can view tilted mountains vividly banded with red and white sandstone and admire the two namesake domes.

A picnic area at road’s end serves as the trailhead for a half-mile hike into Kaolin Wash, where water has carved a steep, winding gash through the rock.

Stone ruins found about a quarter-mile from the picnic area are remnants of the set of The Professionals, a 1966 Western that starred Lee Marvin, Burt Lancaster, and White Domes.

Joshua Trees, Delamar Valley—About 10 miles southeast of Caliente on U.S. 93 is the invisible line separating the Great Basin from the Mojave Desert. A clue that you’ve crossed this boundary is the appearance of Joshua trees, spiky, thick-limbed desert plants that flourish in the Southwestern desert. Mormon pioneers named the trees after the biblical figure Joshua because the uplifted branches reminded them of Joshua praying and pointing to the Promised Land.

You first encounter the Joshua trees at the point where U.S. 93 drops into the Delamar Valley, about 12 miles east of Caliente. First you notice a solitary Joshua in a field of sagebrush and junipers. Then you see another. Soon you’re driving through a veritable forest of Joshua trees.

If you pull off the road for a closer look, you’ll notice how large they are—Joshuas can grow more than 30 feet high. Long, knife-like leaves grow from the branches, which sprout randomly. The trees look less like plants and more like deadly weapons.

Naturalists note that the Delamar Joshua trees are somewhat unusual because they grow beyond the northern limit of creosote bush, one of the indicators of the margins of the Mojave Desert.

Some scientists believe that the moderate local climate and the presence of water have allowed the Delamar trees to flourish where they’re not supposed to be.
