The following five classes of prehistoric cultural features were revealed at the Clampitt site during the 1991-92 excavations:
Feature numbers were also assigned to organic stains which were later determined

A single burned-earth (hearth?) feature (Feature 72, Unit RR) was partially
excavated during the last week of the 1992 season.
