Water has an awesome power of healing, damaging, and destroying. But, can also be calming.
Nugget Falls sits to the right of Mendenhall Glacier and actually flows from another nearby glacier known as Nugget Glacier in Alaska.
The waterfall is 377 feet tall and drops in two tiers with the first being 99-feet and the second at 278 feet into Mendenhall lake, which is freshwater.
Years and years ago, the waterfall was cut short as it flowed onto the glacier, which is still massive, but nowhere near the size it once was. It is said that at one point, the falls were basically non-existent due to the size of the glacier.
As for glaciers, they constantly change by nature. While they form with an accumulation of snow over centuries, they slowly slide away due to the stress of their own weight, they crack and creak.
Glacier's are made of freshwater. The melt-water is important for animals and nature in general as it melts as a source of fresh vs. salt water.
Glacier's are affected by long term climate change, which is why you will often hear talk of glacier melting when climate is discussed. They are sensitive indicators that are often utilized as a map to the climate change on earth.
