Colored pebbles on McDonald’s lake – There is a national park close to the Canadian border, this is Glacier National Park of the U.S. state of Montana. There are about 700 lakes there. Of the many lakes, only 131 lakes have names and 200 lakes are more than five hectares in size. A dozen of these leaves cover thousands of hectares and many are unreachable. The lakes in this national park have very clear water, with very low temperatures during the year so there is no plankton growth. This is what causes the lake to be very clear and not infrequently we can see the bottom of the lake with a depth of up to 30 feet more.
There is an unusual sight in these lakes. It is the presence of colored rocks or pebbles under the surface of the water and the beach and this gives it its own beauty. This colored rock consists of stones with red, dark red, green and even blue colors. The combination of colorful rocks gives a beautiful and unusual impression. McDonald’s lake-colored pebbles are pretty much visible on the west edge of the park.

The beauty of McDonald’s lake pebbles is of particular concern to many local and foreign tourists. Lake McDonald is the largest lake in Glacier National Park. The surface area of the lake is 6,823 acres, with a length of more than 15 kilometers, while the depth of the lake is 141 meters.
Lake McDonald is home to a wide variety of lake natives such as trout and many other game fish. Among the types of fish that can be caught in this lake are west-slope cutthroat trout, bull trout, rainbow trout, lake trout, mountain whitefish, Lake Superior whitefish, suckers, and kokanee salmon.

While beautiful green pebbles are abundant in Lake Otokomi, and dark rocks are found at the upper end of Lake MCDonald.
Along the creek of Lake McDonald and Lake Trout are colored rocks resulting from the heating and pressure of red and green rocks with high iron content. Actually, these natural rocks are around Glacier National Park and were formed in different eras.
When the glaciers come, they prevent the rock from breaking into small pieces and then the river washes it away. Some rocks become sediment at the bottom of the lake. Furthermore, as a result of water erosion, the gravel becomes smooth and slippery. If we quote from the book “Glacier-Waterton International Peace Park” by Vicky Spring and Tom Kirkendall, the process of formation of colored rocks in Lake McDonald is as follows:
“The color of the rock is determined by the presence or absence of iron and the bright red rocks along the Grinnel Glacier were deposited in a shallow marine environment, this is where iron is oxidized by the tidal exposure to the water. Colored rocks often have ripple marks, and ancient mud rift line.”
Green rocks are rocks that form in deeper lakes than red rocks. So, the colorful pebbles in McDonald’s lake are a wonderful gift of nature.

The Lake McDonald park is a legally protected lake. This means that if you come there, you can’t take anything there including colored rocks. Taking McDonald’s lake colored rocks for recreational or educational purposes is prohibited. You can’t take anything home with you.
