The Denver Museum had found its first Folsom point in 1926.[8] It had been embedded in the clay surrounding a large bone; but when Figgins spoke or wrote of this discovery his fellow scientists suggested that the point was “intrusive,” that it had dropped down through a hole made by some rodent. So the next year, when Figgins came upon a Folsom point between two ribs of a bison, he stopped all work and wired to a number of institutions in the East to send witnesses. Barnum Brown of the American Museum of Natural History, Frank H. H. Roberts, Jr., of the Smithsonian Institution, and Alfred V. Kidder of the Peabody Foundation at Andover arrived to view the point _in situ_. Their testimony and the collaboration of Brown in work at Folsom established beyond doubt that man in America had trafficked with animals which were supposed to have been dead by the end of the Glacial Period. Once this was proved, other anthropologists and institutions were off on the trail of more such finds. [Illustration: _The making of a Folsom point. The flint was first flaked to the general shape desired. (This sketch is perhaps a little too schematic.) Next, the maker removed a long flake on each face. Then he retouched the edges, and usually ground the hose and the sides of the ears. (After Clarke, 1940.)_] Americans Hunted Animals Now Extinct The Folsom find was arresting, even dramatic. Not only was one of the nineteen points from the first three field seasons actually lodged between the ribs of an extinct bison. In addition, the skeletons of twenty-three of these animals testified that here was the scene of a prehistoric kill. Man had indeed had something to do with these beasts before they had grown cold; for the tail bones of each bison were missing, and hunters will tell you that, in skinning, “the tail goes with the hide.”[9] [Illustration: _The minute, ribbonlike flaking of a Folsom.

It was rather broad, with a deep concave base that terminated at each side in a jutting point, or “ear.” The edges were most skillfully chipped, and the base and ears were often ground smooth. It was particularly distinguished by the fact that a long flake of stone had been chipped away on each face from the base almost to the tip. The flute, or channel, left by the flake, made the point look a little like the end of a grooved bayonet. This is the true or classic Folsom. An earlier type is larger, without ears, and imperfectly grooved (see illustration, page 155). In current terminology, the former is called simply Folsom, and the other Clovis Fluted, Ohio Fluted, and so on, depending on where the point was found.
