Results of both analyses added support to our suspicions that materials from surface lithic scatters date to different time periods. In some cases, it was possible to Pitt Lake provide relative dates to different surface scatters based on the diagnostic types of projectile points and other artifacts found. Alouette Lake Stave Lake In 2002 a subsurface testing program was initiated to determine the nature and integrity of subsurface cultural deposits at different sites. Radiocarbon dating was employed for contexts where archaeological materials were found in situ. While these proved to be valuable for assessing relative Maple Ridge Hayward Lake significance values of each site for management purposes, they also provided an additional line of evidence to support N the hypothesis of the long-term occupation and land use of Mission Fraser River the drainage area. In addition to the program of evaluative Figure 1. Location of Stave and Hayward Lakes and testing, detailed systematic excavations were undertaken in adjacent landmarks.
