Beverly wedges are usually symmetric elongated bipolarly-pocked tools of shock-resistant quartzite. Often used for splitting organic materials of wood, bone and antler, wedges may be confused with bipolarly struck flakes. Some wedges have double bipolar striking platforms, one on each side of a square. Most, however, have two platforms unless one has been retouched or shattered away. Wedges may have pointed ends, sometimes of differing size. They were used by Déné Indians until replaced by steel axes in the 18th Century. The Déné ancestors of the Taltheilei tradition, and their Barrenland predecessors of the ASTt, Shield Archaic and Northern Plano traditions, used a variety of wedges, but generally their similar splitting purpose obviated a common shape. Like chi-thos and hammerstones, they were simple tools-of-the-moment. There are 45 stratified & 41 culturally affiliated wedges, the latter with affiliation based on other researcher’s assignment; e.g., Wright’s NP & LT wedges from Grant & Athabasca Lakes. Other wedges are called ASTt on diagnostic ribbon-flaking, fine discoidal retouch & associated tools. One surface wedge is labelled ET on its material – phase-specific Aberdeen Lake red taconite. Affiliation is also based on wedge construction on previous phase-specific tools like ET shouldered points. Nonetheless, dozens of surface wedges remain culturally-unassigned. By number and culture, from earliest to latest, stratified wedges include 3 NP, 3 SA, 12 ASTt and 17 ET, 9 MT & 12 LT. Culturally affiliated material includes 16 NP, 11 ASTt and 4 ET, 1 MT and 18 LT. Stratified wedges include 10 rectangular, 13 square, 3 round, 6 rhomboid, 6 parallelogram, 3 tearshaped-triangular & 3 biconvex or ovoid. Affiliated wedges include 10 rectangular, 7 square, 2 round, 9 rhomboid, 5 parallelogram, 6 tearshaped or triangular & 2 biconvex/ovoid. Gross metric and non-metric similarities suggest combining all 86 wedges. Percentagewise, plans are 23% each of rectangular & square, 6% round, 17% rhomboid, 13% parallelogram, 10% tearshaped or triangular, & 6% biconvex/ovoid. That 71 (83%) four-sided wedges occur in all cultures is unsurprising considering four-sidedness doubles wedge function. Most were rotated as seen in their double bipolar flaking. Round wedges occur in ASTt, with one each in ET & MT. NP has all plans except round, SA only 3 plans, ET all save biconvex, MT all except biconvex & tearshaped, and LT all except round. Tundra and forest wedges are 20 & 14% rhomboid and 8 & 19% parallelogram plans, respectively. The elevated tundra rhomboid plan is due to many at the NP KkLn-2 site, while the many forest parallelogram plans in 3 of 4 cultures has an unknown functional connotation. Sections are 7% rectagular/biplanar, 41% biconvex, 27% planoconvex, 7% triangular, 2% concavoconvex, 13% rhomboid/pentagon and 2% parallelogram. Square plans do not occur. Concavoconvex & triangular sections are rarest, with one in LT. SA has biconvex & planoconvex. The remaining cultures have 4 or more sections, with ET having the most. With time, ET drops rectangularity by MT, while triangularity is exchanged for concavoconvexity by LT. This loss of flatter sections in favour of rounder sections may have a functional connotation. Important range differences are absent parallelogram sections in forest and concavoconvex sections in tundra. Parallel sections in tundra are NP & ASTt, while concavoconvex sections in forest are LT. I cannot explain these discrepancies. Possible differences in flaking are now examined. 39 (45%) of wedges have amorphous flake scarring, 33% have columnar scars, 5% are channel-grooved & 15% are combined channel-grooved & columnar. Tundra and forest differences include 40 & 53% amorphous flakescars, 38 & 25% columnar flakescars, 6 & 3% channel-grooving and 14 & 19% combined channel-grooving & columnar flaking. Taken separately, columnar flaking & channel-grooving are higher in tundra, but are higher in forest when combined. Columnar flaking signifies bipolar flaking where flakescars proceed part or all the way from one pole to its opposite pole. Channel-grooving is an extension of the same process, but where one pronounced columnar flakescar bears a groove from pole to pole. This may be a sign of longer wedge use in the forest, perhaps related to scarcer raw material. If so, there should also be more double bipolar wedges in forest. 62% of wedges have simple bipolar percussion, 15% have double bipolar percussion involving rotation, 15% have 3 sharp unused or snapped edges with a striking platform on the fourth edge, and 8% have peripheral scars like a retouched discoidal knife but are struck through rather than transversely to the edge of the wedge. All cultures have bipolarly percussed wedges. SA does not have double bipolar percussion, while LT does not have 3 sharp edges & a striking platform or peripheral percussion. SA wedges are not peripherally percussed. Tundra and forest percussion frequencies are 58 & 67% bipolar, 12 & 19% double bipolar, 18 & 11% 3 sharp edges/single pole and 12 & 3% peripheral or rotational percussion. Forest wedges are used more than tundra wedges, except where they are completely rotated. ASTt wedges in both ranges are heaviest in bipolar percussion, ET has double-bipolar & sharp edges/striking platform in forest only, MT is fully represented in tundra but only bipolar in forest, and LT is similar in both ranges. 71% of wedges are quartzite, 17% are quartz, 10% chert and one is taconite, a culturally diagnostic mineral for ET. From earliest to latest, NP & SA wedges are mainly or wholly quartzite, ASTt adds quartz & chert, ET adds taconite but drops quartz, MT mainly quartzite and LT mainly clear quartz. This oddly high frequency of quartz may have rangewide implications. Taconite occurs only in the forest, which is surprising since the source lies deep in the northeast part of the tundra at Aberdeen Lake near the caribou calving ground. It must have been carried several hundred km southwest to KeNi-4 on the treeline at Whitefish Lake. Tundra and forest material frequencies are 82 & 56% quartzite, 8 & 31% quartz, 10 & 3% chert. Increased forest quartz use over quartzite is due to availability. Indeed, most quartz wedges are from sites dug by James Wright at Lake Athabasca.
