These four 3/4 grooved axes were collected from the White Cloud, Kansas area by antiquarian Mark E. Zimmerman (1866-1933), who donated them to the Highland Mission (now called the Iowa Sac and Fox Mission). Traces of the collector's marks (yellow paint) and labeling are faintly visible on some of the axes. While 3/4 grooved axes are frequently recovered from late Archaic sites, they are also found from other time periods. Axes like these are made by pecking a hard stone into a rough shape and then grinding and polishing it into its final state. They get their name from the hafting groove the encircles 3/4 of the axe's body. It is unknown if these four axes were found near each other, but they all are quite similar in size, ranging from 12.8cm - 11.2cm in length, 7.7cm - 6.6cm in width, and 4.5cm - 3.6cm thick.
