The Bitterroot Mountains are a big part of the Bitterroot Range. They are located in Idaho and Montana in the Western United States. These mountains are also part of the huge Rocky Mountains chain.

The Bitterroot Mountains are made up of two main sections: the Northern Bitterroot Range and the Central Bitterroot Range. Together, they cover a large area of about 4,862 square miles (12,593 km²). The Salish people, who are Native Americans, call these mountains čkʷlkʷqin.

These mountains have natural borders all around them. To the north is Lolo Creek. The Clark Fork River is to the northeast. The Salmon River is to the south. On the east, you'll find the Bitterroot River and its valley. To the west are the Selway River and Lochsa River.

The very highest point in the Bitterroot Mountains is Trapper Peak. It stands tall at 10,157 feet (3,096 meters) above sea level.

Early History of the Bitterroot Mountains

The Bitterroot Mountains were a big surprise for the Lewis and Clark Expedition. This famous journey happened a long time ago. Lewis and Clark were exploring the western parts of North America.

They hoped to find an easy water route from the Atlantic Ocean to the Pacific Ocean. But when they reached the Bitterroot Mountains, they found a very tough obstacle. The mountains were so difficult to cross that they realized there was no easy "Northwest Passage" through them. This changed their plans for the rest of their expedition.
