Prehistoric shaft-like excavations which may have been aboriginal water wells were discovered in the fall of 1949 and the summer of 1950 at the well-known early man site 12 miles southwest of Clovis and 7 miles north of Portales, New Mexico. Work at this site is part of an extended program of geologic studies of Quaternary deposits on the High Plains of western Texas and eastern New Mexico being carried on by the Texas Memorial Museum. A report dealing with the geology and ancient archaeological horizons at the Clovis site will be ready for publication in the near future, but a separate description of the shafts or wells seems desirable at this time.
