Boasting one of the planet’s highest biomass productions, the Tongass National Forest is the largest remaining temperate rainforest on Earth. With its famed ice caves and ancient glacial melt, it encompasses the entire Mendenhall Glacier.
Visit the Mendenhall Glacier in this stunning film:

ASC adventurers and naturalist guides Erica Prather and Andy Davidson spent this past summer sampling freshwater sources in the spectacular Tongass. 

Their film follows meltwater from the Mendenhall as it snakes through Juneau and pours into the open ocean, where it drives a largely intact marine food chain. A window into the magical salmon spawning grounds highlights the interconnectedness of fresh and saltwater systems in Southeast Alaska.
