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.
