Jackpine Shelter Trail Professional Review and Guide
"The Jackpine Shelter Interpretive Trail explores an old forest and its interaction with the surrounding volcanic environment. Despite the Mount St. Helens catastrophe of May 18, 1980, this beautiful, ancient forest grove remains wonderfully intact. The trees, primarily Douglas- and noble firs, were sheltered from the blast— its heat was most severely felt to the north of this area. The trees and forest ecosystem here survived the eruption, but some damage did occur.
This trail explores the Pine Creek Basin, which was gouged deeply by massive mudflows that followed the blast. Farther on, the south flank of Mount St. Helens is visible with all its scars and mantle of gray ash. The route also passes historic Jackpine Shelter, a shack that was built in 1932 to keep backcountry visitors (primarily rangers and hunters) warm and dry."
