The seventh annual John Colter Day will be held on Monday, June 23 at Colter Bay Visitor Center. Colter explored the greater Yellowstone area during the winter of 1807-08, and was likely the first European to travel the region.  To highlight this historical figure, Grand Teton National Park will offer programs on Monday, June 23, including demonstrations of the lives of mountain men of the 1800's and a presentation on John Colter's contributions to the exploration of the American West.  

John Colter Day Highlights include:

June 20-29, 2014 — Colter Stone on Display
This stone—which is on loan from the Teton Valley Historical Museum in Driggs, Idaho— is a piece of rhyolite lava rock carved in the shape of a human head and engraved with the name John Colter, and the year 1808. Discovered in Tetonia, Idaho in 1933, the stone, if authentic, represents the only solid proof of the route followed by trapper and explorer John Colter. As a member of the famed Lewis and Clark expedition from 1804 to 1806, Colter was given an early discharge from the Corps of Discovery. He set out on his own from a fur trapping fort in the southern Montana territory and traveled south to present-day Cody, Wyoming. On his return, he passed through an area that is now part of Yellowstone National Park. A section of his journey is a matter of speculation; one theory indicates he traveled via Togwotee Pass, while the other commonly held view traces Colter's route through Jackson Hole, over Teton Pass and along the west side of the Teton Range.
