This beautiful meadow is high in the mountains, just outside of Los Alamos, NM. It is a very special place. Why?

Answer:

This is the Valle Caldera. A caldera is the crater left when a volcano erupts so violently that it blows the top off of the volcano, leaving a huge, bowl-shaped hole. This one was at least 500 times more powerful than the Mt. St. Helens eruption.
