This chain of lakes in Glacier National Park provides an example of paternoster lakes. In the photo, we are looking towards the northeast. On the map, north is towards the top. The lakes are shown in blue, as are the rivers connecting the lakes. The photo was taken from the trail, shown by a thin, dashed black line on the map, where the camera is located. The lake in the foreground is Grinnell Lake. Behind that is Lake Josephine and beyond that we can see a little bit of Swiftcurrent Lake. These lakes are located in a classic example of a glacially carved U-shaped valley
