THE STORY BEHIND THE PHOTO...

In the heart of Glacier National Park, beyond the waterfall and over the ridge, is Grinnell Glacier. While slowly migrating and freezing and thawing, it grinds against the rock and generates silt-sized particles called glacial flour. As the glacier melts, this glacial flour gets suspended in the water then flows over the falls and into Grinnell Lake, turning what would have been an ordinary mountain lake into this turquoise gem tucked away in the mountains.
