Thousands of years ago, the glaciers that carved the stunning landscapes of Glacier National Park pushed their way down into the modern-day Flathead Valley and sculpted Flathead Lake. The largest natural freshwater lake in the West, Flathead Lake sits in northwest Montana and is a sprawling blue jewel at the base of the Swan and Mission mountain ranges. Encompassing nearly 200 square miles, the lake has 185 miles of shoreline and a depth of 370 feet.
