On our way back to the apartment in Caldwell from Jordan Valley, Oregon, we drove to the Jordan Craters. We really weren't sure what we would find. A well maintained gravel road takes you about 24 miles one way. During the last mile the road got a little rougher. Amazingly, we found lava cones/formations which witnessed to us of a tumultuous eruption in ancient times! This particular field of formations is called "Coffee Cup". We were able to drive down into the formations and get right along side of them while in the car! There is a turn-around at the end of the road with a Bureau of Land Management information exhibit.
These lava fields extend for miles and miles across the expanse. One's imagination can run wild contemplating this severe eruption/s.
