Craters of the Moon National Monument, ID


We woke up in Helena, MT this morning and arrived at Craters of the Moon around lunchtime.  We took some time to check out spatter cones (preserved lava "fountains"), hike up a cinder cone (small volcano), and explore a lava tube.  Tomorrow night will be our first night camping - in Zion National Park!

A snowball fight IN the lava tube! (Not too many people can say they've done that!)


Most of us - we'll get everyone next time.
