Western Stemmed points are large, carefully made bifacial tools with a stemmed base that allowed them to be hafted onto spear shafts.

They differ markedly from Clovis points in their specific form: where Clovis points are characterized by fluting — channels ground into the base of the point — Western Stemmed points typically lack this feature and have a different overall morphology.

The Western Stemmed Tradition has a significant presence in the archaeological record of the Great Basin and adjacent parts of the Pacific Coast.

Some of the sites that have produced Western Stemmed points have been dated to approximately the same age as the earliest Clovis sites — or in some cases, slightly earlier.
