Willey and Phillips (1958) have pointed out the difficulty and
illogicality of attempting to date artifacts exclusively by their
affiliation. Of course, if distinct horizon-markers such as special
forms of pottery are present, perhaps the technique is warranted.
The remains at the LoDaisKa Site do not contain any such limited
horizon markers. Moreover, dating of much of the associated materials
in adjoining areas has, unfortunately, not progressed far enough to
establish chronological limits for any forms. Therefore, it was felt
that geological interpretation might be warranted. This was kindly
undertaken by Mr. C. B. Hunt whose report appears above.
The pre-ceramic levels appear to correlate with the Piney Creek
alluvium (see Hunt, 1954) and deposits equivalent geologically with
the Tsegi Creek alluvium in the Southwest. Elsewhere, Hunt has stated
that the Piney Creek may date about 1-2 millenia B.C., but is possibly
older, (Hunt, 1955). The soil studies (this report) may indicate a
somewhat greater age. Hunt feels that the ceramic levels for the most
part correlate with a period of arroyo-cutting and washing that is
assumed to be later than 1 A.D.
A series of samples for radiocarbon measurement was collected. These
were taken from various areas of the site, some in relatively dry
areas, others from more moist regions. Materials varied from seeds or
plant fragments to charcoal. It was felt that these different materials
would be helpful in indicating the effect of various factors in the C
14 method. The samples were then submitted to Dr. J. B. Griffin, of the
University of Michigan. He kindly accepted the series. The outcome of
the tests and those observations that accrue from the information will
be published as soon as the data are available. A report should be due
in a year. By this study it is hoped to establish fairly exact limits
for certain cultures in the area. In the interpretations of these dates
valuable evidence concerning cultural chronology and diffusion on the
Plains may be gained.
