Mt. Lassen is a national park that few people visit, but it is very interesting.  It is not that far away from Portland and the talk is put together to encourage everyone to make to trip there if they have not seen it.  It has every type of volcanic eruption there in one place, and Mt. Lassen is the largest volcanic dome in the world.  The Cinder Cone in the NE corner of the park is one of the most perfect in the US!  An incredible debris avalanche landslide came off of the top of the volcano and formed the main lake on the west side.  Come and hear Scott Burns talk about one of his newest favorite parks!
