A English settler site wiped out in the 1622
Powhatan Uprising had what appeared to be a
Solutrean blade among the finds, but had no
other materials suggesting that it was
incidentally included. It was assumed to be a
collector item. It's published in:

Buchanan, William T., Jr. and Randolph M.
Owen, Jr. 1981 The Browning Farm Site,
Charles City County. Archeological Society of
VA Quarterly Bulletin Vol. 35.3:139-158.
