MEASUREMENTS: Eight examples from Cave Spring (Moebes, 1974) provided the following measurements: length, 30-45 mm.; average, 39 mm.; shoulder width, 16-26 mm.; average, 22 mm.: stem width, 18-23 mm.; average, 21 mm.: stem length, 10-13 mm.; average, 11 mm.: thickness, 6-9 mm.; average, 8 mm.: basal concavity, 1-3 mm.; average, 2 mm.: width in notches, 10-17 mm.; average, 14 mm.: notch width, 6-10 mm.; average, 8 mm.: notch depth, 3-7 mm.; average, 4 mm.: stem length below notches, 4-6 mm.; average, 5 mm.
FLAKING: Fifty percent show collateral flaking and 50% show random flaking.
FORM: Seventy-four percent of the cross-sections are biconvex, 13% are plano-convex and 13% are median ridged. All blade edges are excurvate. All bases are incurvate. All bases and notches are ground and 75% of the stem edges are ground. Fifty percent have shoulder barbs and all examples are patinated. Thirteen percent have acuminate distal ends and 87% have acute distal ends.
COMMENTS: The provenience of 9 examples, used to define this type of Big Sandy point is as follows: Stratum I; Level 3, 1 (probably out of context); Stratum II: Level 7, 2; Level 8, 2; Stratum III: Level 7, 1; Level 10, 1; Level 12, 2. Five examples of similar type (W4) from Level II at Danger Cave (Jennings, 1957) were dated by radiocarbon samples at 9789 ±630 B.P. and 8960 ±340 B.P. One example was recovered from Stratum II at Flint Creek Rock Shelter, Fig. 55 (Cambron and Waters, 1958).
BIG SANDY BROAD BASE, Cambron (This Paper): A-134
GENERAL DESCRIPTION: This is a medium sized, side-notched, trianguloid point with blade edges that are usually excurvate but may be straight or recurvate. Most examples are serrated. The basal edges and/or notches are usually ground.
MEASUREMENTS: Eleven examples from DeKalb County, Tennessee, 1 example from Warren County, Tennessee, and 3 examples from Cave Spring (Moebes, 1974) provided the following features and measurements: length, 37-53 mm.; average, 44 mm.: shoulder width, 21-38 mm.; average, 25 mm.: stem width, 23-32 mm.; average, 29 mm.: stem length, 11-17 mm.; average, 15 mm.: thickness, 5-10 mm.; average, 7 mm.: basal concavity, 1-4 mm.; average, 2 mm.: width in notches, 17-23 mm.; average, 19 mm.: notch width, 6-9 mm.; average, 7 mm.: notch depth, 3-5 mm.; average, 4 mm.: stem length below notches, 6-10 mm.; average, 8 mm.
