Craters of the Moon National Monument

We continue to venture north and have made it to Southern Idaho.  We spent a few days checking out the volcanic formations at Craters of the Moon national Monument.  The lava field spreads across 618 square miles and is the largest basaltic lava field in the contiguous United states.  The most recent eruption was only 2000 years ago.  There are more than 25 volcano cones in the area.

Sydney was not impressed with this tree mold.

This tree mold is more distinctive.

As is this one.
