Rex Ziak (pronounced "zeek") is a writer, historian, tour guide, and documentarian, who lives in Naselle, Washington, USA. Known for his Lewis and Clark studies, he is the author of In Full View.[1] After careful study of the expedition's journals and of the geography of the Columbia River estuary, Ziak precisely delineated the final leg of the expedition's approach to the Pacific Ocean.
In 2004, Ziak testified before Congress in support of the Lewis and Clark National and State Historical Parks.[2] The next year he published a fold-out map and guide to the route taken by the expedition.[3]
As a documentarian and cinematographer, his work under assignment from ABC Television received an Emmy in 1993. As a local activist and regional historian, he has served as a consultant to the City of Long Beach and as a board member of the Pacific County Friends of Lewis and Clark. Ziak has also run unsuccessfully for local political office.
