That "actual date" is not associated with the oldest
skeletal material.

Rockshelter:
Sheppard et al. (1987): 10,810 +/-300
Hicks (2004): 9,610 +/-40
Floodplain (directly below rockshelter entrance)
Shepard et al. 1984: 10,130 +/-300 "minimum date"
Hicks (2004): 10,570 +/-70
Sheppard et al. never claimed in any publication, 1984 or 1987, that
the
oldest remains were 6,700. End of story.

OK, round up this:
Waters and Stafford (2007) 11,050 minus
Hicks (2004) 10,570 +/-70
equals 480 for the floodplain skeletal material.
or
11,050 - 9,610 = 1440 for the layer closest to the creamation
hearth in the rockshelter.

"Human remains at the site are the oldest that have been found in
Washington,
and at the time was the oldest set of remains found in North America.
Later radiocarbon work has confirmed the original dating of this
site,
indicating that these human remains, albeit very fragmentary, are
still
some of the oldest ever excavated in the New World."
