The Puget Sound Watershed, located along Washington’s Northwest coast, contains 5,467 recorded archaeological sites. 1,290 of which are listed on the National Register of Historic Places. The majority of these sites are located along the coastline and associated waterways making them highly susceptible to climate change induced sea level rise. This research uses data provided from The Washington State Department of Archaeology and Historic Preservation and a geographic information system (GIS) to determine the susceptibility of thousands of sites to rising sea-levels. A mosaic of 10m resolution digital elevation models (DEMS) was created for the Puget Sound Watershed and elevation for each site was then extracted. The data are then compared to predicted sea level rise measurements to generate an inundation vulnerability assessment. Once complete, this research can inform potential management strategies for sites that are currently vulnerable to inundation in the State of Washington.
