Mt. St. Helens Mt. St. Helens before the eruption. The viewing access area is located at milepost 22 on State Route 504.
Visitors can view the dam from a viewing deck or hike the mile trail and walk along the dam itself.

Instead of lifeless landscape, you may see deer and Roosevelt elk grazing, and instead of ash flying overhead, you will see eagles soaring. For your safety, however, these signs of life must be viewed only from the marked trails and viewpoint platform.
