Pillow lava localities in Washington- a new series on Northwest Geology Field Trips

Doing what comes naturally with pillowed lava. Grand Coulee near Lake Lenore.

A page explaining the origin of pillow lava has been added (link). There will be five field trips to diffferent places where pillow structures can be observed in Washington. The first of these has been posted here, to see pillows along the Heart O’ the Hills Road in Olympic National Park.

The other planned pillow field trips are:

  • On the beach at the foot of North Cape Lighthouse, Cape Disappointment State Park (near Ilwaco)
  • Richardson, on Lopez Island
  • Sand Hollow, along the Columbia across from Vantage
  • The Manashtash Viewpoint on I-82, south of Ellensburg

Notices will go out to website subscribers as I get them written. If you wish to send photos and descriptions from other places, please have it! Send writeups to:
