WILD ROGUE Welcome to JORDAN CRATERS! Jordan Craters is a volcanic field, covering 27 square miles with olivine basalt. This otherworldly scene is the result of lava flow that occurred in two main phases, both less than 30,000 years ago. This ancient lava field features craters, lava tubes and pahoehoe (a Hawaiian term meaning “ropy,” describing the smooth, billowy lava flows), showing just how mobile a lava flow can be. Drive right up to Coffee Pot Crater, a well-preserved, steep-sided crater that covers two-thirds of a square mile. Hike through or take photos of this alien-like terrain and explore the area’s beautiful and geologically violent past. Know before you go The area is full of RUGGED TERRAIN, footing is precarious. Lack of trails, sharp lava formations and open pits can be dangerous for the most experienced hiker. LAVA FIELDS can reach temperatures of more than 120 degrees during the summer. Dehydration is dangerous. Bring enough water to remain hydrated. roads are nearly impassable when wet. Winter weather makes access difficult. High-clearance, four-wheel-drive vehicles are recommended. directions Jordan Craters is located in the southeast corner of Oregon in Malheur County. From Highway 95, 8 miles north of Jordan Valley, turn west at the Jordan Craters sign onto Cow Creek Road. Follow BLM Jordan Craters access signs for 25 miles to the site. Contact info don’t forget! 100 Oregon Street Coffee Pot Crater: the only crater on site to offer Vale, OR 97918 vehicle access. This area also features roughly 541-473-3144 aligned spatter cones—blocks of lava that have [email protected] welded together, forming cones. .

OPEN-FILE REPORT 0-92-09 PRELIMINARY GEOLOGIC MAP OF THE JORDAN CRATERS SOUTH QUADRANGLE MALHEUR COUNTY, OREGON By M. L. Ferns, and N. S. MacLeod Oregon Department of Geology and Mineral Industries This unpublished Open-File Report has not been reviewed and may not meet all Oregon Department of Geology and Mineral Industries' standards. Field work conducted in 1990/1991 Map Scale: 1:24,000 Funding Statement: Funded jointly by the Oregon Department of Geology and Mineral Industries, the Oregon State Lottery, and the U. S. Geological Survey COGEOMAP Program as part of a cooperative effort to map the west half of the lo by 2O Boise sheet, eastern Oregon. Jordan Craters South A distinctive, densely-welded, high-silica rhyolite ashflow tuff (Ttlg?) comprises the oldest unit exposed in the Jordan Craters South quadrangle. The ashflow is characterized by high silica and low alumina abundance5 and is correlative with tuffs mapped by Plumley (1984) as Leslie Gulch Tuff in The Hole in the Ground quadrangle to the northwest. If his correlation is correct, Ttlg? is part of the outflow sheet erupted during formation of the Mahogany Mountain caldera tn the northeast. The ashflow is overlain by tuffaceous siltstones (Tsts) and aphyric platy andesite flows (Tmv). Tilted fault blocks comprised of all three units from steptoes around which younger basalts (Tbdb, Tbtm, QTb, Qbcb, Qbrb, and Qbjc) have flowed. The youngest of these (Qbjc) erupted at about 3,000 years ago from a small vent north of the quadrangle at Jordan Crater. The surface of the Qbjc flow is free of wind- blown silt and soil and contains many fragile surface features that are characteristic of very young basalt flows.

Basaltic Volcanism and Tectonics of the High Lava Plains, Southeastern Oregon
AN ABSTRACT OF THE DISSERTATION OF Brennan T. Jordan for the degree of Doctor of Philosophy in Geology presented on June 28, 2001. Title: Basaltic Volcanism and Tectonics of the High Lava Plains, Southeastern Oregon. Redacted for privacy Abstract approved: Redacted for privacy David W. Graham The High Lava Plains province (HLP) of southeastern Oregon is a Miocene to Recent volcanic upland characterized by widespread basaltic volcanism and west-migrating rhyolitic volcanism. New 40Ar/39Ar ages for HLP rhyolites demonstrate that the trend of migrating rhyolitic volcanism is robust, reflecting westward migration at a rate of -35 kmlm.y. from 10 to 5 Ma, and -15 km/m.y after 5 Ma. This pattern mirrors the trend of northeastward migrating silicic volcanism of the Snake River Plain to the Yellowstone Plateau. HLP basaltic volcanism was relatively continuous with episodes of heightened activity at -7.6, -5.9, and 2-3 Ma. The 7.6 Ma event coincided with initiation of High Cascades volcanism suggesting a major regional tectonic event. HLP basalts are variably evolved high-alumina olivine tholeiites. Even primitive basalts are enriched relative to mid-ocean ridge basalts (MORB) in incompatible trace-elements, especially Ba, Sr, and Pb. HLP basalts are isotopically evolved relative to MORB with 87Sr/86Sr of 0.70305 to 0.70508 andENdof +6.7 to + 1.6. Isotopic characteristics of Pliocene and Quaternary basalts are more evolved in the east than the west. Miocene basalts are of more uniform isotopic character. Helium isotopes in Quaternary basalts are constant across the HLP with 3He/4He of -9RA,reflecting either a strongly depleted MORB source or interaction with a mantle plume.

The change in mechanism of mass wasting from upstream to downstream seems to depend on several factors: (1) the ratio of the

ANCIENT VOLCANOES of Oregon
The ANCIENT VOLCANOES of Oregon By HOWEL WILLIAMS CON DON LECTURES OREGON STATE SYSTEM OF HIGHER EDUCATION EUGENE, OREGON . .1953 THE CONDON LECTURES The Condon Lectureship was established in 1944 by the Oregon State Board of Higher Education upon the recommendation of the late Dr. John C. Merriam who was, at that time, a member of the faculty of the University of Oregon. The Lec- tureship was named in honor of Dr. Thomas Condon, the first professor of geology at the University. The purpose of the lectures is to interpret the results of significant scientific research to the nonspecialist. The lectures, usually two annually, are delivered three times in the state, namely, at Eugene, Corvallis, and Portland. They are then published in appropriately adapted form.

Dole STATE GEOLOGIST The ORE BIN Volume 25, No. 3 March, 1963 RECENT VOLCANIC LANDFORMS IN CENTRAL OREGON* By Norman V. Peterson and Edward A. Groh** Introduction As the race to be the first mortals on the moon continues, the questions of how the lunar surface features originated and what rock types they contain are st iII not answered • Many of the lunar configurations that are telescopically visible cer tainly resemble volcanoes and features associated with them . Even if only a part of the moon's surface has been formed by valcan ic processes, some of the smaller volcanic forms; such as hummocky lava flow surfaces, spatter cones, and lava tubes could be present. If these features exist, they could provide ready-made shelters to protect men and vehicles from the hostile environment of radiation, high temperatures, and mef:eorite and dust bom bardment. A reconnaissance of the Bend-Fort Rock area in central Oregon shows that it has a wealth and variety of fresh volcanic landforms that should be of interest to the planners of our lunar programs as well as to the students of volcanology or to those curious about the rocks of Oregon . Recent Volcanic Activity in Oregon Before discussing central Oregon specifically, it may be well to look at the pattern of Recent volcanic activity in all of Oregon.

Jordan Craters Volcanic Field Nick Pollock, Ph.D
14 July 2018 Jordan Craters Volcanic Field Nick Pollock, Ph.D. Candidate Department of Geosciences, Boise State University First, A Note of Caution! The Jordan Craters Volcanic Field contains a few potential hazards to visitors. In the middle of summer, the frequent high temperatures and lack of shade make dehydration and heat stroke a real concern. Make sure you take the proper precautions with sun protection, clothing, and an adequate water supply. Additionally, the surface of the lava flows can be quite unstable. Due to the nature of how they form, the surface of the lava may only be a thin crust above a large void space. Be careful with where you walk, beware of the possibility that the surface of the flows can collapse, and do not stand too close to the cliff edges. And finally, rattlesnakes are a common in the area. Make sure you pay attention to where you are walking and stay aware for rattlesnake warnings. Introduction Jordan Craters Volcanic Field contains a series of Holocene olivine basalt flows located in Malheur County in southeastern Oregon (Figure 1A). The lava flows fill a local depression of the Owyhee Plateau and cover an area of ~72 km2 (extent of lava flows indicated by red outline in Figure 1B). The ~1 km3 of lava filled an area once occupied by Cow Creek (Otto and Hutchinson, 1977), and today two lakes that bound the southeastern end of the lava flows are named Cow Lakes. Coffeepot Crater, the most prominent vent in the region, is found in the northwest corner of the field with the lavas prominently flowing out to the southeast.
