from space showing Crater Lake, Oregon (click to enlarge; north towards upper right.) Technically, it's not a crater at all, but a caldera that remains after the eruption and collapse of Mt. Mazama that occurred around 5,677 (± 150) BC.In one week I will be co-teaching a fully-enrolled field course at this volcano. Can't wait. From the arctic to the volcanic!
