These three bifaces represent just a few of the many that were collected from Elk County and donated to the Kansas Historical Society in 1959. All three are made of Permian chert. The pink colorof two of the bifaces is the result of having been heat-treated prior to their completion in order to make a better knappable chert. Bifaces like these could have been used as a cutting tool or, with more work, turned into a specific tool.
