The MacHaffie site, in the foothills a few miles south of Helena, Montana, is an unusual open site in that it has three occupation levels. Folsom Fluted points occur in the bottom; Scottsbluff points in the middle; later types of points comparable to Signal Butte II come from the top level. In 1938 A. J. Harstad, an amateur mineralogist from Helena, discovered the site. He saw flint and bones projecting from a cut bank; he later pointed these out to E. D. MacHaffie, also of Helena. In a surface survey, MacHaffie discovered artifacts of a late type, and Mrs. MacHaffie also found a Clovis Fluted point in the small creek near the site and possibly from the site itself (Fig. 62, 12). On a later visit MacHaffie found a point of Scottsbluff type on the surface. At this time he dug into the cut bank and found bones, chips, and some flaked knives.
