Craters of the Moon

We spent a good portion of today hiking some of the trails in the park. The lava was deposited in several eruptions starting 15,000 years ago. The latest was a mere 2,000 years ago. We had a discussion with a Ranger and he seemed to be convinced that the hotspot under the park wasn't done erupting. They have 4 seismometers located around the park and there has been some activity detected. He estimated 100 years. There are several lava tube caves scattered around the lava field. Hikers are allowed to enter 2 of then. That is on tomorrow's agenda.
