The beauty of Saint Mary Falls cannot be overstated. With its fast current and roiling turquoise waters, it is a must see at Glacier National Park. The blue-green color is created when fine glacial material known as rock flour floods into the lakes and river during snowmelt. Rock flour is very light, and stays suspended in the water. When the light hits the surface the rock flour distorts the
wavelengths of light, reflecting back more of the green and blue end of the spectrum. This artwork and pattern was produced as Artist-in-Residence at Glacier National Park.
