destroyed all but slight surface protuberances. An extensive test 

 failed to recover any apparent details of construction, and no artifacts 

 were secured. 



ARTIFACTS 



The definitive artifacts from 13JH2, with a single exception, are 

 entirely surface finds. 



1. Leaf-shaped points with a flat or slightly concave hasal termination {sam- 



ple: 4). Plate 23, a. 



Range of length: 63.0 mm. (one complete example). 



Range of width : 22.0-31.0 mm. 



Range of thickness: 9.0-11.0 mm. 



Cross section : Roughly biconvex. 



Technique: Percussion. 



2. Points with parallel sides and concave bases. Basal area symmetrically 



tapered to a chisel edge (basal thinning). A single example (13JH2-5) * 

 is characterized by an earlike basal barb (sample: 3). Plate 23, &. 



Range of length: 71.5 mm. (one complete example). 



Range of width : 18.0-22.0 mm. 



Range of thickness : 7.0-12.5 mm. 



Cross section: Biconvex, notably thick except in basal area. 



Technique: Percussion, well controlled. 



3. Fragment, leaf-shaped point, shallow concave base (1SJE2-28). Plate 23, c. 



Length : 



Width : 25.5 mm. 



Thickness: 6.5 mm. 



Cross section : Biconvex. 



Technique: Pressure, well controlled. 



Depth : 0.7 foot below surface, in old Crosheck mound group area. 



Typologically, this specimen closely resembles the sample described under 



No. 1 above, yet it is sharply separated from it in refinement of form 



and technique of execution. 



4. Elongate triangular point with convex base, base beveled symmetrically to 



a chisel edge (13JH2-20). Plate 23, d. 



Length: 58.5 mm. 



Width: 15.5 mm. 



Thickness: 9.0 mm. 



Cross section: Roughly biconvex. 



Technique: Percussion, poorly controlled. 



5. Miscellaneous point fragments. 



a. Flat base, deep corner notch (13JH2-27). 



6. Apical fragments, probably deriving from examples similar to Nos. 1, 

 2, or 3 above (sample: 3). 



6. "Thumb scraper," convex bit, abrupt bevel to acute scraping edge, fragmen- 



tary (1S.JH2-11). 



Length : 23.5 mm. 



Width: 23.0 mm. 



Thickness: 9.5 mm. 



Cross section : Plano-convex. 



Technique: Percussion, use pressure.
