Columbia Muleear Point

The artifact exhibits a compact, angular morphology, ranging from triangular to pentagonal in shape, with a distinctive elliptical profile in cross-section. Its asymmetrical form is often accentuated by a recurvate or incurvate curvature, lending a dynamic quality to its overall appearance. The basal edge varies in curvature, spanning a spectrum from subtle concavity to pronounced inward curvature. The flaking pattern observed on this specimen is characterized by a non-directional, random arrangement of flake scars.

The dimensions of the arrowheads are characterized by a total length ranging from 34 to 55 mm, with a mean length typically falling between 36 to 41 mm. The maximum width of the blade varies from 19 to 41 mm, averaging between 23 to 28 mm. Additionally, the basal concavity measures between 3 to 7 mm.

This type is mainly located in the southern areas of the Columbia Plateau, but can also occur with less regularity in the central to northern parts of the Columbia Plateau

The Mule Ear point derives its name from its distinctive appearance, which emerges after undergoing multiple re-sharpening processes. This characteristic shape is a result of the intentional reworking of the artifact, likely to extend its functional lifespan. As noted by Heath in 2003, the Mule Ear point's unique form is a testament to the resourcefulness and ingenuity of its creators, who carefully re-sharpened and reconfigured the tool to maintain its effectiveness. This phenomenon highlights the importance of considering the life history of an artifact, including the various stages of use, reuse, and modification, in order to gain a deeper understanding of the cultural and technological contexts in which it was created.
