Lakes and Mountains Near USA-Canada Border
Several lakes are visible admist the mountain peaks and snowy terrain of this upper of the northern United States (below, from left to right: Washington State, Idaho and Montana) and southern Canada (above, from left to right: provinces of British Columbia and Alberta).
Flathead Lake, in the lower right quadrant closer to the right edge, is located in the northwest corner of the state of Montana, 7 miles (11 km) south of Kalispell. It is approximately 30 miles (50 km) long and 16 miles (25 km) wide, covering 191.5 square miles (495.9 km²).
The lake is bordered on its eastern shore by the Mission Mountains and on the west by the Salish Mountains. The Flathead Valley was formed by the glacial damming of the Flathead River and sustains a remarkably mild climate for a region located this far north and inland; the Pacific Ocean is almost 400 miles to the west.
To the northwest, in the center of the image, Kootenay Lake appears as a large, upside-down “Y”. It is located in Canada, between the Selkirk and Purcell mountain ranges in the Kootenay region of British Columbia. It is one of the largest natural lakes in British Columbia, at approximately 100 km in length and 3-5 km in width.
It is, in part, a widening of the Kootenay River, which in turn drains into the Columbia River system. Although oriented primarily in a north-south configuration, a western arm positioned roughly halfway up the length of the lake stretches 35 km to the town of Nelson.
