Jordan Craters

Area of Critical Environmental Concern - Oregon

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.

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 Vale, OR 97918 541-473-3144 BLM_OR_VL_Mail@blm.gov Coffee Pot Crater: the only crater on site to offer vehicle access. This area also features roughly aligned spatter cones—blocks of lava that have welded together, forming cones.
Jordan Crater BLM crater are collapse pits, probably formed by the collapse of lava tube roofs. Flow structures include pahoehoe (a Hawaiian term meaning “rope” or “ropy” that describes smooth, billowy lava flows), pressure ridges, and lava gutters that illustrate how mobile molten rock can be. Know Before You Go Please be careful. You can get a bad cut if you fall on the lava. In addition, temperatures on the lava field can exceed 120 degrees during the summer, leading to dehydration and heat exhaustion. Coffee Pot Crater, the only feature to which there is vehicle access, covers about two-thirds of a square mile and is a well-preserved, steep-sided crater. One of the most interesting features in the vicinity of Coffee Pot is a sequence of roughly aligned spatter cones. They consist of blocks of lava, probably ejected in a semi-molten state, that have welded together, forming cones. The interiors of the cones have a glassy “furnace lining” look because they were vents for hot gasses. Fishing, photography, and exploring are all popular activities. Directions to the Site Jordan Craters is located in the southeast corner of Oregon in Malheur County. From Highway 95, eight miles north of Jordan Valley, turn west at the Jordan Craters sign onto Cow Creek Road. Follow BLM Jordan Craters access signs 25 miles to the site. From a distance the lava field appears dark, as if shaded by a cloud.

An 18-acre flow within the field is thought to be l than 100 years old bause not even lichens have begun to colonize it.
