At 10,157 feet in elevation, Trapper Peak rises higher than any other peak in the 200 mile-long Bitterroot Mountain Range along the Idaho-Montana border from the Snake River Valley in Idaho to the Clark Fork River in Montana. The range included howling wilderness, yawning canyons, and towering mountains covered with a heavy growth of pine and fir, and huge sheets of ice carved the granite mountain and left glacial landforms known as horns, cirques, moraines, and aretes that give the massive mountain its jagged form and distinctive profile. Trapper Peak has witnessed human activity in the Bitterroot Valley for at least 8,000 years, from prehistoric hunters and gatherers to the Bitterroot Salish, who thrived in the valley until 1891, when they were moved to the Flathead Indian Reservation. In 1805, members of the Lewis and Clark Expedition passed here, followed by traders, trappers, and missionaries. In 1877, the non-treaty Nez Perce passed peacefully through the valley on their way east while fleeing the U.S. Army. Mining, agriculture, and logging brought settlers, and in 1876 Granville Lee Shook, a surveyor for the Anaconda Mining Company, named the mountain for its trapping success. Trapper Peak's timeless and sturdy form represents history from the travelers of the past to the modern-day traveler of tomorrow.
