The
Colter Stone, discovered near Tetonia, Idaho in 1933, is a
piece of rhyolite carved in the shape of a human head. It
is engraved on one side with the name John Colter,
on the other side is the year 1808. If authentic,
it represents the only solid proof of the route followed by
trapper and explorer John Colter.
Colter explored the greater Yellowstone
area during the winter of 1807-8, perhaps the first white
man to do so. His route, however, is uncertain as no clear
maps or records exist. Colter set out from a fur trapping
fort in present-day southern Montana and headed south to near
todays Cody, Wyoming. On his return he passed through
what is now Yellowstone National Park. The middle section
of his journey is a matter of conjecture. One theory indicates
he traveled via Togowtee Pass. The other commonly held view
traces Colters route through Jackson Hole, over Teton
Pass, and north along the west side of the Teton Range. No
evidence exists to substantiate either route. The only available
sources of information are vague accounts and maps derived
from interviews with Colter after his return.
Thus, the significance of the Colter
Stone becomes clear. The location of its discovery, the west
side of the Teton Range, would prove that John Colter had
traveled the Teton Pass route. But the Stone has not been
fully authenticated, so the Colter Stone remains a fascinating
piece of the puzzle yet to fit into the mystery of John Colters
pioneering sojourn through this region.
