Three peculiar carved stone objects from eastern Montana merit mention, because carved biomorphic forms are otherwise almost entirely absent from this area (Fig. 27).

One was found on the surface about twenty miles south of Glendive, Montana. It is a vaguely trapezoidal piece of rather hard pumice 4.7 inches high, 5.1 inches wide, and 3.5 inches thick, which had been smoothed throughout, apparently with a rubbing stone, though on the back and sides many irregularities remain. A large, flat area has been smoothed on the bottom, apparently to provide a base. On one side an excellent representation of a bison head has been carved in bas-relief. The background has been so reduced that the head is elevated .3 inch above it. The whole has been well smoothed and rounded and only a few striations remain which suggest that the work was probably done with a stone chip or similar tool. Each eye has been accentuated with a daub of what appears to be pitch.
