Additional Comments:

This point has been refer to as the En Medio point, the Basketmaker II point, and the Hueco point.  These points may represent the same technologies or continuum of technologies with a slight regional difference.  The name Hueco or Basketmaker II has been applied to points with a wider thinner blade with wide notches and a narrow neck while other points found at the same location that have a slightly narrower blade may be classified as San Pedro points.  The overall stylistic attributes may have slight variation, the technology remains the same. (Justice, 2002).

En Medio name was used by Cynthia Irwin-Williams for examples found at En Medio shelter in New Mexico.  These have also been associated with the Basketmaker II.  Smaller examples associated with the Basketmaker III were typed Trujillo by Irwin-Williams.
