This group of 15 bifaces (chipped stone tools worked on both sides) was found in Atchison County, sometime in the late 19th- early 20th-century, by a boy plowing a field. A cache is a group of items stored or hidden for future use. All of the bifaces have been heat treated to improve their knapping qualities and with additional work, could have been turned into specific tools. The original cache contained 16 bifaces. The landowner gave the cache to George Remsburg, who passed it to fellow antiquarian Mark E. Zimmerman. It then came to the Kansas Historical Society in 1925, where it continues to be the focus of research.
