Saint Mary Lake

Saint Mary Lake is a stunning glacial lake located in Glacier National Park, Montana, in the United States. The lake is named after St. Mary, the mother of Jesus, and is one of the largest lakes in the park, measuring about 9.9 miles (16 km) long and up to 300 feet (91 m) deep. The lake is surrounded by towering mountains, including Mount Gould and Saint Mary Peak. The vivid blue-green color of the lake water is caused by glacial flour, which is finely ground rock particles that are washed into the lake by the tributary streams. Saint Mary Lake is a popular spot for boating, fishing, and hiking, and is known for its pristine water and magnificent scenery. Visitors can access the lake via the Going-to-the-Sun Road, which offers breathtaking views of the lake and the surrounding landscape.
