Amazing place in Montana: you will be surprised by a lake filled with colourful pebbles

Lake McDonald is considered the coldest and most photogenic lake in Glacier National Park in Montana. It is filled with amazing colourful pebbles and deserves a place on the list of the best locations.

Lake MacDonald is the largest lake in Glacier National Park. According to the park service, it stretches 10 miles in length and is nearly 500 feet deep. This is the result of glacial carving that also shaped the surrounding valleys, which are home to several spectacular waterfalls, writes Simplemost.

But what really sets this lake apart from the 700 lakes scattered throughout the park are the colourful pebbles that look like they were individually painted and dropped into the lake.

Several factors go into creating the coloured stones. First, according to the park service, the lake's temperature rarely rises above 50 degrees Fahrenheit at the surface. These cool temperatures inhibit plankton growth, allowing visitors to see detail on the lakes' bottoms, even at depths of 30 feet or so.

As for the colours of the rocks, when the glaciers arrived, they chipped away at the rocks from the surrounding mountains, which were different colours with shades of red and green. That's how this amazing lake appeared, which amazes tourists.
