- FlUa-1, Skoglund's Landing: This is a multicomponent site, about 13.7 m above maximum high tide. GSC-1290 gives a maximum age for deformation of strata overlying the cultural deposit. These strata appear to have reached their present position by creep, land-slding, or slumping. GX-1628 is inconsistent with the artifact assemblage in that it is far too young. The charcoal which produced this date may have come in with the slope wash which covered zone II. GX-1696 was associated with a hearth intrusive from zone II into zone III. Although slightly more recent than expected, it is considered reliable and probably indicative of the age of the main zone II occupation. S-675, from the upper component, was associated with 1500 flaked basalt artifacts including primarily retouched flakes and bipolarly percussed forms. It is an acceptable date. In addition to the dated components, there is a small assemblage of flaked stone tools that suggest human occupation older than 8000 years BP, but
