mountaineering- Glacier Peak

This is one possible plan for the summer but I need to upgrade my equipment and prepare for this physically. It is sometimes hard to find people who want to go to this extreme but I will talk some people into this adventure. The peak is located in a large National Forest wilderness Area. This is a roadless area, on public land, that is set aside as wilderness- The Glacier Peak Wilderness Area. Has anyone been hiking in the Cascade Range-which stretches from N. California through Oregon and Washington states to S. BC Canada????? I have hiked different portions of the Cascade Range in all the above areas and climbed Mount Adams- another volcano.

climb Glacier Peak in the North Cascade Range of Washington State. It is a volcano, composite or the explosive type- ka-boom!!


Glacier Peak is a small stratovolcano in the Cascade Range of Washington. There are over one dozen glaciers on the sides of this volcano. Most of the loose pyroclastic deposits have been eroded by these glaciers. The tops of the ridges to the northeast of the volcano are covered by lava flows. Small basaltic flows and cones can be found around the sides of Glacier Peak. Lava flows only extend a few km from the top of the volcano. Three hot springs flow from the ground around the volcano. Fresh looking dacite domes are positioned high on the north and south sides of the volcano. Warm ground and areas without snow surround these domes. Large fans of pyroclastic materials almost entirely fill the valleys on the east and west sides of the volcano.



Most of the eruptions from Glacier Peak have been tephra eruptions. Two tephra layers from the volcano stretch up to 500-600 miles (800-1000 km) to the east. These layers were deposited about 11,250 years ago.
