Named by Gordon Willey in 1949. This seems to be just a single motif within the broad category of Swift Creek Complicated Stamped. It does not seem necessary to name Crooked River as a separate type.
Complicated stamping on sand-tempered pottery. The designs are rectilinear zigzag lines or chevrons in a herringbone-like manner. The chevrons are continuous down the side or around the body of the vessel. This is an early Swift Creek type with the marker notched and/or scalloped rims-thus the type name. The interiors of the vessels are smooth. Vessels are straight-sided pot forms with rounded bases.
