Guilford Concave Base
AKA: Guilford YumaCluster:
Description of Physical Characteristics and Flaking Pattern:
This is a thick medium (1.9 to 4.75 inches) lanceolate point with a cross section that may vary from elliptical to having a median ridge. The blade is excurvate with the tip curving in and curving back in towards the base. The base is concave. Basal grinding is present on this point. This point has a random flaking pattern.
Size Measurements:
Length - 40 to 120 mm (average 65 to 95 mm ), Width -15 to 35 mm (average 25 to 30 mm), Thickness - 5 to 12 mm, Basal Concavity - 1 to 3 mm

Additional Comments:
At the Doerschuk site, these points were found above Morrow Mountain points and below Halifax points (Coe, 1959).
These points are thought to have evolved into the Conerly points.
