Conservation Corps

“One of the reasons I chose to volunteer at Mount St. Helens was my connection to the land. My great-grandparents had a cabin near Ariel, and I spent a lot of time there as a child. The first place I volunteered at was Ape Cave—a place I had visited a hundred times as a child. So it was meaningful to me to help improve it.”

- Katherine Bilyeu, MSHI Conservation Corps & Mountain Steward Volunteer

We love Mount St. Helens, and want to make sure that the mountain is accessible and healthy for those who visit the Mountain today, as well as 20 or 50 years from now. Conservation corps volunteers help us achieve this goal by volunteering for a variety of projects, some of which include: trail maintenance, invasive weed removal, building upkeep, habitat restoration, and more.
