Understanding the coastal watercourses that shape the sanctuary landscape and watershed transition.
Mapped Streams and Hydrologic Features of Olympic Coast National Marine Sanctuary
The streams of Olympic Coast National Marine Sanctuary represent critical hydrologic connections between the rugged Olympic Peninsula terrain and the protected marine environments of the Pacific. This collection identifies natural watercourses within the sanctuary scope, emphasizing their roles as drainage channels that feed into the productive nearshore and continental shelf ecosystems. By tracing these channels, users gain insight into the complex boundary where inland forest runoff meets the high-energy tidal and upwelling zones of the Pacific coast.
