Join us in celebrating Alaska Day here at beautiful Mendenhall Lake, just a stone’s throw from the state capital of Juneau. It seems a timeless sight, but the lake actually began to form in the early 1900s as Mendenhall Glacier receded, leaving a deeply carved valley in its wake that was soon filled with glacial melt. Today, the glacier still feeds the lake, much to the delight of the many visitors who arrive in Juneau each summer on cruise ships.
