Truman Trail— Pumice Plain Professional Guide

Detailed Trail Description from our Guidebook

"Hike across the lonely Pumice Plain deep into the heart of the blast zone. Once desolate, the plain now teems with wildflowers, willows, and other flourishing flora, and birds and mammals too. Cross creeks and hummocks and skirt wetland pools, enjoying unique views of Spirit Lake and Mount St. Helen’s growing and smoldering crater dome."
