Loyd Doty reports:

AUX ARC (Expanded Stem) – is French meaning ‘bend in the river’ and describes a large bend in the Arkansas River near the Aux Arc recreation area midway between Fort Smith and Clarksville, Arkansas.  This point type was named by amateur Leon Dunn for examples recovered from sites in that portion of the Arkansas River.  It is a medium sized (2” to 3”) projectile and knife with expanded blades, strong shoulders that are round or straight and a straight stem with expanded base that is straight or slightly concave.  There are two variants of the type, the Hurricane and the Harris.  Distribution includes Arkansas, Missouri, Oklahoma and they were in use during the Middle Archaic period.
