Rivers and Mountains in Idaho

Rivers in Idaho

Bear River
The Bear River has a total length of 563 km and flows through the states of Idaho, Wyoming and Idaho. The Bear River is created in Utah by the confluence of the Hayden Fork and Stillwater Fork. From there it flows through the southwestern part of Wyoming, from there to Idaho and finally flows back to the Great Salt Lake in Utah. The Bear River is particularly important for agriculture because it is used very intensively for irrigation.

Bruneau River
The Bruneau River is an approx. 246 km long tributary of the Snake River. Its catchment area is the Jarbidge Mountains, from which it flows through Idaho (Owyhee County) and Nevada (Elko County). The Bruneau River is particularly popular with fans of white water: rapids, warm springs and the 370 m deep and 64 km long Bruneau Canyon make the area an ideal tour.

Salmon River
The Salomon River is a 684 km long river that once flows through central Idaho. It rises from the Sawtooth and Salmon River Mountains and has a height difference of approx. 230 m from source to mouth in the Snake River (on the Oregon border). It is considered the longest undamaged river in the United States and the longest that flows through a single state. Due to its rapid rapids, the Salmon River is particularly popular with fans of white water rafting, but it is not entirely safe. In some areas you can only go on the water with permission, because accidents on the river without recurrence are not uncommon.

Snake River
The Snake River is also known as the Shoshone River and has a length of approximately 1,674 km. It is a tributary of the Columbia River and flows through the states of Wyoming, Idaho, Oregon and Washington. The source of the river is in Yellowstone National Park and from there the river also flows through the Grand Teton National Park. The Snake River flows into the Columbia River near the city of Pasco. The Snake River flows through numerous deep canyons and forms many waterfalls, such as the over 60 m high Shoshone Falls.

Mountains in Idaho

Borah Peak
Mountains with a height of more than 3,000 m are not uncommon in Idaho. At 3,859 m, Bora Peak is the highest of them. It is located in the Lost River Range Mountains in Custer County and was named after the US Senator William Edgar Borah. It is also known as Chickenout Peak because many mountaineers mostly cancel their hike up.

Cache Peak
At 3,151m, Cache Peak is the second highest mountain in the state. It is located in the south-central Idaho in the Albion Mountains and is the highest point in Assia County and in the region of the Snake River.

Pot Mountain
At 2,176 m, Pot Mountain is the highest mountain in the Clearwater Mountains (part of the Rocky Mountains) in Clearwater County. The view is unimaginable, because the mountain range is surrounded on three sides by the picturesque North Folk Clearwater River.

Bitterroot Range
The Bitterroot Range is a mountain range along the border between the states of Idaho and Montana and is one of the Rocky Mountains. The Bitterroot Range has a length of approx. 489 km and a width of approx. 431 km. The Bitterroot Range is named after the plant Bitterwurz (English bitterroot), which is also the state plant of Montana. The highest peak in the Bitterroot Range is the Scott Peak with a height of 3,474 m.

In summer, Bear Lake is a popular destination because of its beaches, but also because of its deep blue color. Anglers will also find a good place here.

Coeur d’Alene Lake
With about 175 km of shore length, Coeur d’Alene Lake is in northern Idaho. It is about five kilometers wide and a popular lake for relaxing, paddling and fishing. However, the EPA (Environmental Protection Agency) does not recommend eating fish caught in the river. Due to the years of mining in the region, he was contaminated by heavy metals. Due to the construction of the dam on the Spokane River, its height has risen to 637 m above sea level.
