History
Flathead County was founded in 1893. Some sources cite the supposed practice of the Salish tribe flattening infants' heads as the origin of the name Flathead, but there is no record of Salish Indians ever having that appearance.
Geography
The county includes much of Flathead Lake, the Flathead Valley, and the Flathead River. These natural treasures were created by glacial activity which ended approximately 10,000 years ago. The Flathead Valley is the southern extension of a prominent valley called the Rocky Mountain Trench, which runs from the Yukon Territory in Canada as far south as Flathead Lake. The Trench in northwestern Montana was created by subsidence along a major extensional fault, which continues today. After the valley formed, glaciers flowing down the Trench from British Columbia, and into it from the surrounding mountain ranges left a flat valley floor and dammed the Flathead River drainage to create Flathead Lake. Several tribes have long used the Flathead Lake, and the Bitterroot Salish, Kootenai, and Pend d'Oreilles tribes are represented on the Flathead Reservation. The western part of Glacier National Park is located in the county.
According to the United States Census Bureau, the county has a total area of 5,256 square miles (13,610 km2), of which 5,088 square miles (13,180 km2) is land and 169 square miles (440 km2) (3.2%) is water. It is the third-largest county in Montana by land area and second-largest by total area.
