Jordan Craters Area of Environmental Concern

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.
• The lava fields can reach temperatures of more than 120 degrees during the summer. Dehydration is a very real and very dangerous possibility. Bring enough water to remain hydrated.
• Roads become nearly impassable when wet.
• Winter weather can make access difficult.
• High-clearance, four-wheel-drive vehicles are recommended.

Point of Interest

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 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.
