Rick Thompson

Rick Thompson, author of "GigaFlood: The Largest of the Lake Missoula Floods in Northwest Oregon and Southwest Washington", and co-author of "The Hunt for Iceberg Erratics", is an Oregon-born artist, entertainer, writer and self-taught geologist who loves to share the beauty of the great Northwest.

Though geology is not his profession, it is his passion. Being intrigued by the land formations, huge boulders and glacial erratics, Rick embarked on a twenty-plus-year study of the area to understand the effects of the Ice Age Floods in the greater Portland/Vancouver area. His PowerPoint talks and book signings are very popular and often set attendance records.
