The Jordan Craters in Oregon are a unique and fascinating geological feature located in the high desert of southeastern Oregon. These craters were formed around 15,000 years ago during the Pleistocene era, when a massive volcanic eruption occurred in the area. The resulting lava flows covered an area of approximately 100 square miles, creating a series of craters and other geological features that are still visible today.
The Jordan Craters are located in a remote and isolated area, and are not easily accessible by road. However, they can be reached by hiking or driving off-road vehicles over rough terrain. The craters are surrounded by sparse vegetation, including sagebrush and other desert plants, and are home to a variety of wildlife, including jackrabbits, coyotes, and rattlesnakes.
There are several different types of craters at the Jordan Craters, including cinder cones, spatter cones, and lava tubes. Cinder cones are small, steep-sided volcanoes that are formed when volcanic ash and cinders are ejected into the air and then fall back to the ground, forming a cone-shaped structure. Spatter cones are similar to cinder cones, but are formed when lava is ejected into the air and falls back to the ground, forming a cone-shaped structure. Lava tubes are underground channels that are formed when the surface of a lava flow cools and solidifies, while the molten lava continues to flow beneath the surface, creating a hollow tube.
One of the most striking features of the Jordan Craters is the Great Rift, a massive fissure in the earth's surface that runs for over 30 miles through the area. The Great Rift is thought to have been created by the massive volcanic eruption that formed the craters, and is now a popular spot for hikers and off-road enthusiasts.
Despite its remote location, the Jordan Craters have a rich history and are an important part of the cultural and natural heritage of southeastern Oregon. They are a testament to the power of Mother Nature and the forces that shape our planet, and are well worth a visit for anyone interested in geology or the natural beauty of the high desert.

The proposed national monument is within the Oregon Biodiversity Project's Middle Owyhee River Conservation Opportunity Area. The cone is made of lapilli and bombs. Sometimes the lava flowed around points of higher land, leaving the vegetated kipukas. Fluid basalt outflow from Coffeepot Crater was fed by lava pond spillover and an extensive tube system that infilled topographic lows to build a prominent smooth to hummocky to ropy surfaced pahoehoe flow field that extended up to 10 miles from the crater. What To Do There are two major visitor entrances: Cow Lakes and Coffeepot Crater. Photo courtesy of the Oregon Department of Geology and Mineral Industries. Sections of the original crater wall were rafted away by lava from the pond, which was later infilled by thin pahoehoe sheets as the pond was reestablished.
We truly love working to bring you the latest volcano and earthquake data from around the world. Late Holocene environments on the northern periphery of the Great Basin. Seattle: The Mountaineers Books. A short interpretative walk available is at Coffeepot Crater. After checking out the BLM Cow Lakes cowground for yourself, take the West Peninsula exploration below.

We need financing to increase hard- and software capacity as well as support our editor team. Contains the following named places: Bench Reservoir, Blowout Reservoir, Blue Canyon Reservoir, Claude Reservoir, Coffeepot Crater, Coffeepot Reservoir, George Ranch, Glover Reservoir, Groundhog Reservoir, Holdout Reservoir, The Pinnacle Ranch Airstrip, Wild Rose Reservoir. Late Cenozoic volcanic stratigraphy of the Jordan Valley area, southeastern Oregon. Aerial view near Coffeepot Crater showing cone, pit craters, and pahoehoe lava. A lava pond once filled the crater and broke through and rafted away part of the cone. Turn west left on a good BLM road signs say "Jor- dan Craters". University of Nevada Press, p.
Continue west on a county road, following signs to Cow Lakes. Sage grouse, mule deer, and pronghorn can often be seen herds of the latter sometimes swim at night to the island in Lower Cow Lake and can be seen in the moonlight. Inflated basaltic lava — examples of processes and landforms from central and southeast Oregon. To reach the do-not-miss Coffeepot Crater, drive approximately 8 miles north of Jordan Valley on US 95. Coffeepot Crater is the most prominent feature in Jordan Craters. This volcanic field contains excellent examples of features associated with basaltic volcanism.
Coffeepot Crater, shown above, was one of the main vents. Volcanically speaking, Jordan Craters may well not be extinct. The campground is set in a crested wheatgrass seeding, and cattle have free range among the picnic tables. Print size is approximately 24" x 27" This quadrangle is in the following counties: Malheur. Over three hundred species of wildlife, including white pelican, long-billed curlew, and bald eagle, have been counted in the area.
Maintaining our website and our free apps does require, however, considerable time and resources. Jordan Craters National Monument Proposed Suggested Citation: Kerr, Andy. Hence the vegetation is pristine. More recent Bannock—Northern Paiute peoples may have witnessed a spurt of activity from Jordan Craters within the last few hundred years, based on accounts passed on to EuroAmerican explorers and settlers in the 1800s about fire and smoke coming out of the ground. The flows dammed local river valley, forming the two small Upper and Lower Cow Lakes at the SE end of the lava field. Scientists have discovered 18 acres of the bare lava that's really bare—no lichens and mosses. Special thanks to Rosemary Kenney.
Geological Survey Bulletin 217, 83 p. Backflow of the lava pond into the conduit marked the final activity at Coffeepot Crater, leaving behind pahoehoe crust on the crater floor and vertical striations carved into the inner crater walls. Flows to the south in the Clarks Butte area are much older and more covered with vegetation. Printed on high-quality waterproof paper with UV fade-resistant inks, and shipped rolled. They provide excellent and diverse wildlife habitats.
Located about eighteen miles northwest of the town of Together with pristine basalt volcanic features, this seemingly unforgiving terrain supports localized habitats that are rich in fauna, earning it a designation as a Israel C. The terrain is essentially too rugged for domestic livestock. Jordan Craters is a monogenetic volcanic field in southeast Oregon. To visit Cow Lakes from Jordan Valley, go west approximately 5 miles south- bound in the grander scheme on US 95, which then turns to the southwest. Jordan Craters is an otherworldly place, beautiful and foreboding, an outdoor museum of recent basalt volcanism amid sagebrush steppe rangeland. The Caxton Printers, Ltd.
Because of the diversity of habitats, the presence of water, and the lack of livestock, wildlife thrive. . The map contains contour lines, roads, rivers, towns, and lakes. Journal of Volcanology and Geothermal Research, v. Geological Survey Scientific Investigations Report 2018—5140, 40 p.
BLM brochure, Chitwood, L. If only they could be trained to use those fancy outhouses. Lava near the vent is shelly pahoehoe. The Coffeepot Crater volcano was born when mildly explosive eruptions constructed a cone from overlapping lobes of dense and fragmental ejecta the material thrown out from a volcano. One particular petroglyph site, which stands guard over a portion of the Jordan Craters lava flow field, presumably overlooked important hunting and gathering grounds in ancient wetlands prior to basalt emplacement.
