2017 Map of Tunnel Island

About this map

Tunnel Island and the neighboring sea stacks of Elephant Rock and Little Hogsback define this coastal stretch of the Olympic Peninsula within Grays Harbor County. The landscape is characterized by its dramatic interface with the Pacific Ocean, where steep elevations at Pratt Cliff drop toward a series of offshore features including Willoughby Rock, Split Rock, and Flat Rock. Inland, the terrain is shaped by a dense network of Bureau of Indian Affairs routes, such as Bia RD 7000 and Bia RD 7565, which navigate the drainages of the Raft River and Whale Creek. The distribution of these roads reflects the modern management of these forested lands, providing access to the various forks and tributaries like North Fork Raft River and Camp Creek that carve through the coastal hills.
