The prehistoric sites located within Los Peñasquitos Canyon provde a relatively intact sample to study Late Prehistoric organizational behavior. Hunter-gatherer subsistence-settlement strategies are reflected by intersite variability in the archaeological record. The organizational variation of hunter-gatherer societies is a result of differing environmental constraints. Binford (1980) provides a forager-collector continuum model for explaining subsistence-settlement strategies. This study explains the Peñasquitos subsistence-settlement strategies using Binford's (1980) model with site record forms and survey-level data.
