First evidence of the development of the Marpole culture in the San Juan Islands: The Marpole culture was a land-based hunting people with little evidence of a marine economy. Their artifacts were characterized by rude chipped stone points and implements with some use of deer antlers but few bone points. This culture named after the Marpole site on the Fraser River flourished through all the islands until about 400 AD.
