Mt. St. Helens erupted on May 18th 1980 8:32 a.m.  An
earthquake shook the Volcano.  Steam came out  of cracks in
the volcano top.  A side of the volcano blew off and ash flew
everywhere.  Everything was covered in ash.  

     In the mudflow houses were lifted off the ground and trees
were knocked  down.  Melted snow caused an avalanche that
made  the mudflow.

      Colonizers are animals that came after the eruption.  Plants
are also colonizers.  Seeds blew in with the wind.  Survivors
buried themselves underground like the Pocket gopher.  If the
pocket gopher didn't come out of the hole arter the eruption and
cover the ash with seeds that flew in wouldn't grow.

     Links are inportant because if we didn't have them we would
die because there would be no food.  Like if the gopher didn't
cover the ground with dirt seeds that flew in wouldn't grow and
animals that eat those plants would die and meat animals would
die because there would be no food for them to eat
