Places to Visit in Eastern Oregon #2
Steens Mountain and Alvord Desert
Steens Mountain and the Alvord Desert form one of the most dramatic geologic landscapes in the American West, a place where the forces of faulting, volcanism, and ice have created a stunning visual contrast. Steens Mountain is not a typical mountain range but a massive, 50-mile-long fault-block mountain, a single slab of basalt that was uplifted and tilted westward by tectonic forces over millions of years . Its western slope is a gentle, gradual incline, while its eastern face is an escarpment that rises abruptly, creating a sheer wall of rock and eroded gorges that tower over the valley floor. At its summit, reaching 9,733 feet, visitors stand at the apex of this colossal geologic structure, looking out over a landscape that reveals over 17 million years of volcanic history .
Directly below this imposing eastern front lies the Alvord Desert, a vast, otherworldly playa that exists in the rain shadow of the mountain. The desert is a graben, a flat basin that dropped down as the mountain rose, creating a closed basin with no outlet to the sea . Where Steens Mountain receives considerably more moisture, the Alvord is the driest location in Oregon, receiving less than seven inches of rain annually . This aridity, combined with the basin's topography, creates an environment that feels more like a distant planet than part of the Pacific Northwest—a vast, cracked expanse of alkali dust stretching for miles to a hazy horizon . The white, cracked surface of the playa is the remnant of ancient Lake Alvord, a deep pluvial lake that filled the basin during the Ice Ages, leaving behind salt minerals when it evaporated .
The ecological diversity of the region is as striking as its geology. The dramatic range in elevation on Steens Mountain—from the Alvord's 4,000-foot floor to the nearly 10,000-foot summit—creates distinct life zones in a relatively short distance . The base of the mountain features salt-tolerant plants like saltbush and greasewood, transitioning upward to vast sagebrush steppe and juniper woodlands. Higher still, sheltered canyons give way to groves of quaking aspen and lush, wildflower-strewn meadows, culminating in an alpine tundra zone near the summit with hardy plants more typical of the Rocky Mountains . This vertical diversity provides habitat for a wide range of wildlife, including mule deer, pronghorn antelope, and the iconic California bighorn sheep, as well as the famous Kiger mustangs, a herd of wild horses with a distinctive color and conformation .
The Alvord Desert, despite its harsh conditions, is also home to unique life, sustained by the same fault system that created the dramatic landscape. Throughout the region, the thin, faulted crust allows geothermal energy to escape in the form of hot springs. The most famous of these is Alvord Hot Springs, where 170°F water emerges at the base of the mountain and is piped into a man-made pool, offering a soothing soak with a view of the vast playa . More ecologically significant is Borax Lake, a smaller, hotter spring site that is home to the endangered Borax Lake chub, a small fish that has evolved to survive in water temperatures that can reach 100°F . These oases, along with other springs like Mickey Hot Springs with its dozens of vents, provide critical water sources for all life in this arid land, from migratory birds to the bands of wild horses that come to drink .
For visitors, the Steens Mountain-Alvord Desert region offers an experience defined by profound solitude and a palpable sense of the West's frontier spirit. The area is remote, with the town of Frenchglen serving as a primary gateway on the mountain's western side and the tiny outpost of Fields, famous for its milkshakes, on the desert's southern edge . A popular route is the Steens Mountain Loop Road, a gravel road that climbs from the sagebrush lowlands to the summit, offering jaw-dropping overlooks into the glacier-carved gorges of Kiger, Little Blitzen, and Big Indian canyons . On the other side, the Alvord's flat, hard-packed playa becomes a destination in itself, where people camp under some of the darkest skies in Oregon, drive or land small aircraft on its surface, and witness sunsets that set the rugged face of Steens Mountain ablaze with color . It is a landscape of extremes that rewards the adventurous traveler with a sense of discovery and a deep appreciation for the raw power of nature.
