Buchanan Eared
Cluster: Humboldt Cluster Description of Physical Characteristics and Flaking Pattern:
This is a medium to large lanceolate point with an elliptical or median ridge cross section. The blade has an outward recurved shape, flaring out towards the base. Some examples may have weak shoulders above the ears, while others will have a straight blade up to the point that the base flares out forming ears. The base may vary from concaved to notched. The classic flaking pattern is oblique transverse, but also may have a random flaking pattern.
Size Measurements:
Total Length - 25 to 125 mm (average 35 to 45 mm), Max Blade Width - 14 to 32 mm, Basal Width - 18 to 31 mm, Basal Concavity - 3 to 7 mm, Thickness - 6 to 11 mm

Additional Comments:
This point is considered to be a variant of the Humboldt point. A similar Humboldt type, Humboldt Expanded Base has a Great Basin distribution. It has been suggested that the Buchanan Eared and the Humboldt Expanded Base may represent the same type. Buchannan Eared are often found in association with Mendocino Concave Base which is often considered the same as the Humboldt point. Humboldt Expanding Base are often found in association with Humboldt points.
