San Juan Island and Mt. St. Helens







On Saturday and Sunday I was on San Juan Island in Puget Sound. On the rocks around South Beach I noticed glacial striations. I have also posted a shot from the top of the island looking southwest toward the Olympic Mtns.

Today was a very good day. I traveled south to make a pilgrimage to Mt. St Helens. The photo of me shows the crater in the background with the stream-carved pyroclastic flow from the 1980 eruption at the base of the volcano. The material visible in the stream bed under the pyroclastic flow is from the landslide that immediately preceded the eruption in May 1980. The lava dome is visible in the crater.
