Tatshenshini-Alsek Park area has been called "North America's wildest river. It is a land where wild, vast rivers cut their way through ice clad peaks, creating lush valleys that are home to extensive wildlife populations. Here glaciers descend to waters' edge, shearing off thunderously into icebergs. Surrounded by national parks, the Tatshenshini-Alsek headwaters run through the subarctic tundra of the Yukon's Kluane National Park, the middle reaches flow past the towering peaks of the St. Elias range, and the lower river traverses Alaska's Glacier Bay National Park to finally arrive at the Pacific Ocean. For its extraordinary scenic and wildlife values the area was named a UNESCO World Heritage Site in 1994. (source: www.spacesfornature.org)
