| Road Guide to Volcanic Deposits of Mount St. Helens and Vicinity, Washington |
by Michael P. Doukas
This road guide is a tour of Mount St. Helens volcano and vicintiy, with emphasis on the effects and deposits of the 1980 eruption. The road log starts at the U.S. Geological Survey's David A. Johnston Cascades Volcano Observatory, Vancouver, WA. The guide is organized around two primary routes. Leg 1 is on paved and gravel roads from Vancouver to areas east of Mount St. Helens, including the Windy Ridge Overlook near Spirit Lake. Leg 2 leads to areas west of the volcano from Vancouver via U.S. Interstate Highway 5, then on a paved and gravel road along the Toutle River. Highlights include the spectacular effects of mudflows and a view of the huge debris-avalanche deposit that was formed on May 18, 1980. |
