Travel to Mt. St. Helens and environs, from Portland, with a naturalist guide who will discuss the geology, ecology, climate, history, and legends of the area, as well as the history of US public lands. Your guide will lead you on hikes near waterfalls, through lava tubes, and within oldgrowth forests.
You will see some of the most unique geological features in North America, including North America's longest continuous lava tube and a lava tree mold forest. Weather permitting, you will be driven to the closest viewpoint into the crater of the volcano, where you will be provided a picnic lunch, overlooking Spirit Lake. No matter how hot the weather, you'll enjoy natural air conditioning as you hike by dramatic waterfalls and through primeval forest. You'll have the option of a dinner/beer stop (own expense) on the way back to Portland.
