Context
bison bone bed with Goshen projectile points. Bone from bone bed. considered best date. Date places the Upper Twin Mt site as being younger than the northern Plains Goshen complex and slightly older than the southern Plains Plainview complex, although it nearly overlaps with the oldest Plainview dates. Possibility exists that this date indicates that Goshen and Plainview are not contemporary, butr rather form a continuous sequence (begins in the N Plains/Rocky Mts and ends several thousand years later in the S Plains (Kornfeld 1998:52).
