The shoreline at Kalaloch is a broad, sandy, bluff-backed beach at the southern end of the coastal strip in Olympic National Park. The location of this distinctive notable shoreline along the coastal Highway 101 corridor, as well as its proximity to the popular Kalaloch Lodge and associated cabins and campground, make it one of the more valuable beach access points on the coast. The coastal bluffs at Kalaloch have been eroding at various rates since at least since 1974 based on available analyses of the site. Erosion at this site presents a variety of management problems, placing buildings and recreational infrastructure at risk. A variety of approaches have been employed to monitor and understand patterns of erosion of the bluffs at Kalaloch that will be summarized in this presentation, including ground surveys with GNSS, conducted at least twice annually, and often seasonally, since 2013. The results of those ground surveys can be coupled with available aerial lidar to provide insights about trends in morphology and position of coastal bluffs at Kalaloch between 2002 and the present. To complement the ground surveys, in October 2023 five Chronolog community-science photo monitoring stations were installed along the bluffs at Kalaloch. In addition to results associated with ground surveys, we will describe early insights provided by the first winter of photos submitted at those stations.
