History of Big Hole River

The Big Hole River and its surrounding area were a popular trade route for Native Americans and a place to forage.

However, no one stayed in the area year-round due to the harsh winters in the area. Later on, the area was popular with trappers in the 1800s. Notably, Lewis & Clark also traveled through this area.

The Big Hole River began to be settled by miners and homesteaders in the mid-1800s to early 1900s. A.J. and Hattie Noyes were the first homesteaders in the valley, and they settled in Crossings, now known as the town of Wisdom.

With the gold rush, more people began to move to Montana and near the Big Hole River. With meat becoming wanted by miners, ranchers also started moving to the area. Today, many of the ranches that started then are still operating today.

Although the history of the Big Hole River is relatively peaceful, there was one infamous violent event. The day of August 9, 1877, the U.S. Army attacked the Nez Perce tribe. The Nez Perce were able to flee the battle, but many people were lost in the battle.

Today the battlefield is preserved and is now the Big Hole Battlefield National Monument.

Today Wisdom and Jackson both have rather small populations but a thriving rancher community. The areas remain popular with tourists for outdoor recreational activities.

The Big Hole River is about 153 miles long, making it somewhat large. It starts at Skinner Lake and ends at Jefferson River. The watershed drains about 2,800 sq miles.

The valley is in a high-altitude area and is surrounded by mountains. It is about 6000 feet above sea level. Because it’s so high up, the valley is quite cold even in the summer months.

The river flows through the mountains for a bit and then makes its way through the Big Hole valley for about 60 miles. Then it goes eastward and enters a canyon. At this point, the velocity of the river has picked up and there are a few rapids.

After traveling through the canyon, the river goes South past the small town Divide. This area is surrounded by cottonwood trees. 

Then after 25 miles, the river flows northeast and flows into the Jefferson River.

Due to the moisture of the area, Big Hole River is also known for having quite a few mosquitoes. Visitors will want to plan on bringing bug spray to avoid an unpleasant trip.

The Big Hole River is also famous for being the last area in the United States with native fluvial Arctic Grayling.
