The connection, nay partial identity, of this culture with that of the Thompson River region in the southern interior of British Columbia is supported by considerable evidence. Small heaps of fresh-water clam shells are found in both regions. The preponderance of chipped points over those ground out of stone, bone and antler; the presence of digging stick handles; pestles with flaring bodies and no striking heads, others with tops in the form of animal heads; celts; the sites of cache pits, of circular summer lodges marked by rings of stones; and of semi-subterranean houses with stones on the encircling ridge; pairs of arrow-shaft smoothers, and bone tubes, were all found to be common to both regions. The simple pipe bowl found here, although with one exception not found among archaeological objects in the Thompson area is commonly used by the present Indians there. Tubular pipes, modern copper tubes or beads, incised designs consisting of a circle with a dot in it and engraved dentalium shells, each of a particular kind, besides pictographs in red, rock-slide sepulchres, modern graves walled up with parts of canoes, the marking of recent graves with sticks, and the custom of burying artifacts with the dead were also found to be common to both areas. Perforated slate tablets of gorget-form are unknown in both regions. Circles of stones which mark places where cremated human remains were found in this region sometimes indicate graves in the Thompson River region. Frazer[432] mentions meeting Yakima Indians in the Lillooet Valley which shows that they travelled even beyond the Thompson River country and readily accounts for the dissemination of cultural elements.
