Located on the east side of Glacier National Park, the basin which holds ten-mile long Saint Mary Lake was gouged during the Pleistocene Epoch by a huge glacier which originated high on the sides of Mount Jackson and Logan Pass less than fifteen miles upcanyon. 8,881-foot Red Eagle Mountain rises above the morning mist at the top right of this photograph taken during early October when the cottonwoods and grasses along the lake have taken on their autumn hues. The pointed summit of 8,792-foot Split Mountain rises in the center of the image. 15,000 years ago, the center of Glacier National Park was a vast icecap spilling glaciers far out onto the Great Plains. This horizontal photograph was captured with a 6x7 format camera. All photos in these fine art photo galleries may be ordered as fine art framed prints or for stock photography usage.
