Stuffed, we started off to see the Craters of the Moon National Monument and Preserve, a huge area that has been the site of numerous lava flows in the last 14,000 years or so.
As we drove, we saw some precipitation in the distance. It started to rain. Then it started to snow. Then it started to be a white-out. On June 2, this was our first view of Craters of the Moon:
These flows have been happening approximately every 2000 years since about 14,000 years ago. They may have been caused by leftover heat from the same super hot-spot that migrated through the Snake River plain and is now under Yellowstone.
