Volcanic Lake

The story goes:

There was a volcano in Mexico, but what nobody knew was that there was natural springs going on under there.  One day instead of a volcanic eruption, water errupted instead and turned the volcano into a lake!  Cousins and us went to this perfect cirlce lake and at the top of the mountain there are eating spots, so my aunt make good food, we hung out and walked around the lake at the base of the mountain
