These rocks are actually all around Glacier National Park, and were formed at different eras. When the glaciers came, it broke down the rocks into tiny fragments and the rivers washed them away. Many of these got deposited onto the lakes and "tarns" —lakes formed by filling the bottoms of ice-scoured amphitheaters. Water erosion then rendered them into smooth pebbles. One of the most striking feature of some of these lakes is the presence of a variety of colored rocks and pebbles just below the water surface and on the shores. The rocks range in color from dark red to maroon, and from green to blue. Colored pebbles are seen in abundance on the shores of Lake McDonald on the western side of the park. Lake McDonald is the largest of the lakes of Glacier National Park with a surface area of 6,823 acres. It is also the longest, at over 15 km, as well as the deepest lake at 141 meters.
