Summary

Sometime between 1931 and 1933, William Beard and his son discovered a rock carved into the shape of a man's head while clearing a field in Tetonia, Idaho, which is immediately west of the Teton Range. The rhyolite lava rock is 13 inches (33 cm) long, 8 inches (20 cm) wide and 4 inches (10 cm) thick and has the words "John Colter" carved on the right side of the face and the number "1808" on the left side. The stone was reportedly purchased from the Beards in 1933 by A.C. Lyon, who presented it to Grand Teton National Park in 1934. Fritiof Fryxell, noted mountain climber of numerous Teton Range peaks, geologist and Grand Teton National Park naturalist, concluded that the stone had weathering that indicated that the inscriptions were likely made in the year indicated. Fryxell also believed that the Beards were not familiar with John Colter or his explorations. The stone has not been authenticated to have been carved by Colter, however, and may have instead been the work of of later expeditions, possibly as a hoax, by members of the Hayden Survey in 1877. If the stone is ever proven to be an actual carving made by Colter, in the year inscribed, it would coincide with the period he is known to have been in the region, and that he did cross the Teton Range and descend into Idaho, as descriptions he dictated to William Clark indicate.
