Birch Creek Lanceolate
Cluster: Description of Physical Characteristics and Flaking Pattern:
This is a narrow medium ovoid to lanceolate point with an elliptical to plano convex cross section. The blade is excurvate, curving in at the tip and becoming almost parallel (Type A) and curving back in towards the base (Type B). The base ranges from straight to slightly concave (Type A) to convex with rounded basal corners (Type B). This point has a random flaking pattern.
Size Measurements:
Total Length - 44 to 75 mm, Blade Width - 15 to 26 mm, Thickness - 5 to 8 mm

Additional Comments:
Granger and Ireland (1986), note that this type rarely appears in literature. Butler first uses this name, and illustrates them, for examples found on the mouth of the Portneuf River, but does do describe the type. Swanson, King and Chatters names and describes Type A and Type B. They also mention a Type C, but does not describe or illustrates this type. The full distribution on this type is not mentioned by Swanson or Butler.
