Great Falls is known as the “Electric City” because of its numerous dams and power plants. Montana’s second largest city is located on the Missouri River among the five falls that were both a magnificent spectacle and formidable barrier to early river travel.
This area held great significance for the Lewis and Clark Expedition. The explorers were forced to spend nearly a month portaging around the falls in June 1805. Much of the Missouri River in this area remains as it was when Lewis and Clark first viewed it over 190 years ago.
