- FdMi-1, Steeprock Lake: The site is situated on two terraces, the upper one relatively undisturbed, the lower one modified by an early high water level of the lake. Cultural materials associated with the upper terrace relate to late Palaeoindian, Early and Late Archaic. The early component appears to be dominated by Early Archaic tool forms with Simonsen/Logan Creek affiliations. It is overlain by later undisturbed cultural materials. Wilmeth (1978: 116) provides a summary comment: Since the samples were dated in two series, the following remarks summarize two sets of comments by Hlady. All three dates are from a dark red sand layer which includes Agate Basin, Plainview, and Archaic side-notched projectile forms. This is overlain by gray-red sand which includes a crude flat side-notched/ basal-notched McKean variant and thin crude eared stemmed corner-notched points. Below the dark red sand, which varied in depth and thickness, was a sterile light red sand. Hlady believed the first date obtained (S-479) was too recent for the older assemblage, and that the shallow firepit may have been an intrusion from the gray-red sand zone. Commenting on two dates obtained later, he points out that while the colour variations were readily evident in the profiles, the changes were extremely difficult to recognize while trowelling downward. Arbitrary two inch levels were therefore used. However, this use of the surface as a datum, while adequate for measuring the position of artifacts, is inappropriate for relating the position to the strata across the site. But if the top of the sterile light red sand, assumed to be the surface when site habitation began, is used as a datum, and if the carbon sample positions are plotted as distance above datum, then there is a surprisingly consistent relationship between position and time.
