The following overview is an excerpt (Page 2016) from the final report of the Game Creek Data Recovery Project.
The excavations at Game Creek produced evidence for nineteen components, 10 of which are supported by multiple radiocarbon dates, spanning much of the Prehistoric period.
Even with high precision AMS dates, the age estimates for these components, calculated at 2 sigma, span 100-400 calibrated years.
Consequently, it is likely that multiple components are represented in some of the pooled mean dates.
In 2010 WYDOT authorized a data recovery project to mitigate adverse impacts to the Game Creek site arising out of the proposed highway expansion. Approximately 200 square meters of the site was excavated with some blocks reaching depths of two meters.
Over 170,000 artifacts were recovered, including 1,164 stone tools and 39,176 faunal remains.
Eckles and Rosenberg (2002) recommended that the site receive formal evaluative testing in the event of future impacts.
In the summer of 2002 OWSA personnel under the direction of Dan Eakin excavated 18 1-x-1-m test units, 59 shovel tests and five backhoe trenches to assess the presence, extent and integrity of subsurface cultural materials (Eakin and Eckerle 2004).
Initial work at the site consisted of a systematic pedestrian survey and the excavation of six shovel tests.
Written for archaeologists and amateur collectors alike, the book describes over 50 types of stone arrowhead and spear points according to period, culture, and region.
With the knowledge of someone trained to fashion projectile points with techniques used by the Indians, Justice describes how the points were made, used, and re-sharpened.
Charcoal from a fire-cracked rock concentration identified in the wall of trench 1 at approximately 50 cm below the surface in stratum IV was dated to 3860±40 during testing of the T3 terrace.
However, two Late Paleoindian projectile point fragments, a Haskett and a Lovell Constricted, a Late Paleoindian Cody knife and an Archaic Elko Eared/Hanna point fragment were found in disturbed contexts.
