Chipped stone tools from 34RM446, a typical Late
Archaic Twilla phase campsite and chipped stone tool workshop in the Thurmond
Ranch archaeological survey area, Section 33-13N-24W. The dart points from
34RM446 are virtually identical to those which have been recovered from Late
Archaic bison kills in northwestern Texas and western Oklahoma (cf.
Bement and Buehler 1994, Hughes 1973).
