“One of the Most Remarkable Sights on the Continent”
On September 5th, an easy ford of the river permitted the entire party to cross in 15 minutes. The next day the Bighorn Mountains came into view as “faint blue clouds” in the distance. Around noon, the party arrived at the confluence of the Bighorn and Little Bighorn, near present day Hardin, Montana. As they passed through the broad valley of the Bighorn, the party found what Raynolds called “the three great requisites, wood, water, and grass” to be plentiful. Travel was fast and easy, in one day they logged 17 miles.
On September 9th they finally arrived at the mouth of the canyon. A stunning impression was made upon Raynolds who stated it was “one of the most remarkable sights upon the continent.” The river flowed “out through reddish tinted walls of perpendicular rock over 300 feet in height.’ The party advanced up to an “impassable wall of rock.”
At this point the expedition halted to make sketches and geological observations. The next day they would leave the vicinity of the canyon, heading south and east. They would skirt the Bighorns until eventually going into winter quarters along the Oregon Trail, near present day Casper, Wyoming.
A Lasting Legacy
While rightly known for the first scientific descriptions given of Yellowstone, the expedition also literally put Bighorn Canyon on the map. The canyon was no longer the subject of legend or mountain man lore, it was now a landmark that would see further explorations in the coming decades. The Raynolds expedition had opened Bighorn Canyon to wider public knowledge.
