In 2014 and 2015, Inlailawatash crews and Nation representatives identified several previously unrecorded rockshelter sites in the Indian River Valley. Further analysis of hearth samples collected by Inlailawatash at one of these sites, DjRr-4, revealed key insights into land and resource use by Coast Salish peoples. Using a combination of micromorphology of sediments, phytolith and diatom analysis, paleobotany, zooarchaeology, lithic analysis and radiocarbon dating, this work shows DjRr-4 was used periodically as a base camp for hunting by 1300 years before present. The site was used during the first introduction of bow and arrow technology, likely as a station along a trail that connected the coast to interior regions.
