History
The Copalis Native Americans belong to the coastal division of the Salishanlanguage family and historically occupied the area of Copalis River and the Pacific Coast between the mouth of Joe Creek and Grays Harbor. In 1805, Lewis and Clark estimated a population of 200 Copalis in 10 houses. The 5 individuals assigned to a "Chepalis" tribe in an enumeration given by Olson of the year 1888 probably refers to them. The first non-Native American people settled in Copalis Beach in the 1890s. Copalis, along with the beach of the same name, has become famed as the "Home of the razor clam." The community sits near the northern end of probably the greatest razor clam bed in the world for the flavor renowned variety abounds, apparently only in the Pacific Northwest, and particularly on Copalis Beach. During the commercial season, Copalis' normal population of about 350 persons, leaped fourfold. During 1947 and 1948, commercial diggers took more than a million pounds of bivalves from Copalis Beach, earned themselves approximately $200,000.00 and brought huge additional sums to cannery men and workers. Tourists dug thousands of pounds more.
