Black obsidian side-notched point with a flat contracting base; the entire point is curved to the right of the dorsal side. M. Christopher 10/16/1998. Dr. Dennis Jenkins, University of Oregon, sent this specimen to Northwest Research Obsidian Studies Laboratory, Corvalis, OR for analysis (on loan 11/30/98 - 4/9/99). A portion of this specimen was removed for obsidian hydration. The source of raw material was determined to be Cougar Mountain. Northwest Research Obsidian Lab placed a paper tag in the specimen bag with the following information: [Lab Contract #] BO-98-91 [Catalog #1989-57/35-M-] 75 [Collection Name] Bergen [Analysis] Specimen No: 35 [Source Location] Cougar Mountain See also the following report from Northwest Research Obsidian Studies Lab for more detailed analytical data: Skinner, Craig E. and Jennifer J. Thatcher 1998 "X-ray Fluoresence Analysis of Artifact Obsidian from the Bergen Site, Fort Rock Lake Basin, Lake County, Oregon." Northwest Research Obsidian Studies Laboratory, Report 98-91, Corvalis OR. Dr. Jenkins' interpretation of the data was reported at the Northwest Anthropological Conference, 4/8/99 - 4/10/99 in his paper entitled, "Obsidian Characterization and Hydration Results of the Fort Rock Basin Prehistory Project." D. Bradley 04/12/99.

Irregular shape. Thin with retouched notch on one edge, slight retouch on pointed end.

Brown.

None

Irregular shape. Thin with light retouch on alternating sides.

Stone war club.* Tapered, broken on one end, bifurcate knob on one end. Also knobbed on the other end. Probably a salmon packing pestle (6/95). *Information is from the original accession ledger.

Round sinker.* Single groove. (6/95). *Information is from the original accession ledger.

Gray.

Triangular. Concave, brown.

Jade celt or chisel.* Fide donor GTE: Jade celt or adze, greenish black, showing cutting grooves. Jade, serpentine and other tough, fine grained stones were used for making celts, chisels and adzes for all wood working and for cutting and dressing skins. Boulders cut in two, smoothed on one surface and grooved, are found on old village sites and camping places. These are most always of greenstone, of jade and serpentine. And when they occur in many flat worked pieces of a coarse silicious sandstone with one or more beveled edges which just fit the deeper grooves in the boulders which would seem to indicate very clearly that these were the knives or saws by means of which the boulders were cut in convenient sized pieces to be worked on: the slightly concave grindstones into tools. The people of the present day have little or no knowledge of this art or manufacture. The grooves show a convex a flat or a concave goove along the bottom but more often is the convex surface apparent. Some of the tools thus cut are finished throughout their length while others are rough splinters merely brought to a cutting edge. In most of the celts and chisels, one or more grooves are plainly visible where the section was cut from the stock piece. Greenstone was universally used for cutting tools and in the following catalogued specimens (2882-2898) the term jade is used to describe those that from their weight and hardness would appear to be of that mineral, although a chemical analysis would be necessary to determine their material structure. *Information is from the original accession ledger.
