St. Mary Lake
Glacier's 762 mountain lakes are stunning for their sheer size and the towering mountains rising from the shores of their
clear waters. Little Chief Mountain imposes a formidable flank over this high-altitude lake. Second in size to Lake McDonald,
St. Mary is often frozen completely over in winter with ice up to 4-feet thick.
