We had three correct answers to our November’s What Is It. Terry Cook of Fort Morgan, Colorado; Patty Echel-meyer of Denver, Colorado and Fred Clark of Colorado Springs, Colorado all correctly identified the objects as prehistoric stone axes. These are all lower grade tools. Two lack the shape and workmanship of finer examples. The two celt type axes are much smaller and have significant damage to the bit ends.
Thank you for venturing a guess. You have all won a year’s subscription to the Mountain States Collector.
