An Archaeological Reconnaissance of Northeastern Baja California and Southeastern California

Abstract

This paper deals with the. archaeology of the northeastern region of Lower California and the southeastern portion of California. Evidence derived from these aboriginal remains indicates two possible cultural horizons, late prehistoric Yuman pottery making groups and an earlier non-ceramic group.Most of the data have been derived from Baja California, because the area north of the International Boundary line has been so severely pot-hunted that sites fail to yield data in sufficient quantities for analysis. The area covered in this report comprises some nine hundred square miles, bounded by the Coast or Peninsular Ranges, the Superstition Mountains, and the Sierra de los Cocopas, and including the southwestern part of Imperial Valley and the northern half of Laguna Salada in Baja California.
