The prominent feature on this side is a large worn

concave grinding surface area that measures 11 inches

(7.9cm) long, 8 1/2 inches (21.5cm) wide and 5/8 inches

(1.5cm) deep. Since axes were also smoothed or polished

on their sides it's possible that this side was used for

that purpose. There are also at least 12 small holes on this

side that may have been used for cracking nuts.
