The Prehistoric Cultural Sequence at Crescent Beach, British Columbia.
This thesis is a delineation of the prehistoric cultural sequence at Crescent Beach in Surrey, British Columbia. It has been derived from intensive examination of data recovered during 4 ½ weeks of salvage work at the site.
Analysis of the rescued materials and of other artifacts from the site now held in private collections, points to continuous occupation for a period of not less than 5,000 years. Comparison of these materials with the assemblages from other peripheral sites indicates that the chronological sequence at Crescent Beach is composed of a series of components that mirror a number of the traits that are diagnostic of some of the conceptualized units of prehistoric culture in and around the Lower Fraser-Gulf Islands region. The cultural units definable at Crescent Beach from the earliest to the latest are designated as follows: Crescent Beach I, Crescent Beach II and Crescent Beach III. The first of these, Crescent Beach I, bears demonstrable affinities to the Mayne phase and is characterised by an artifact assemblage in which lithics are predominantly chipped. In Crescent Beach II, which relates closely to the Locarno Beach phase, there is a proportionate percentile rise of ground stone artifacts in the phase's lithic assemblage. Additionally, shouldered projectile points first appear in the component. Crescent Beach III, which corresponds to the Marpole phase, is typified by the almost complete demise of implements based upon cobbles. Later components analogous to the Stselax and San Juan phases were not found intact in the cultural deposits. However, evidence of their existence at the site is contained in the highly disturbed upper zone and also the many private collections of prehistoric materials gathered at the site by long-time residents.
