Misty Fiords National Monument
Misty Fiords National Monument (or Misty Fjords National Monument) is a national monument and wilderness area administered by the U.S. Forest Service as part of the Tongass National Forest. Misty Fiords is about east of Ketchikan, Alaska, along the Inside Passage coast in extreme southeastern Alaska, comprising of Tongass National Forest in Alaska's Panhandle. All but are designated as wilderness. Congress reserved the remainder for the Quartz Hill molybdenum deposit, possibly the largest such mineral deposit in the world. The national monument was originally proclaimed by President Jimmy Carter in December 1978 as ''Misty Fiords National Monument'',〔(Proclamation 4623 - Misty Fiords National Monument ) of December 1, 1978〕 using the authorization of the Antiquities Act and became a part of an ongoing political struggle between the federal government and the State of Alaska over land use policy and authority that finally led to the Alaska National Interest Lands Conservation Act in 1980.〔Alaska Humanities Forum: (ANILCA )〕 In that law, it was statutorily established as ''Misty Fjords National Monument''.〔(Alaska National Interest Lands Conservation Act – PUBLIC LAW 96-487-DEC. 2, 1980 ), Sec 503〕
==Physical geography==
John Muir compared the area with Yosemite Valley for its similar geology and glacial morphology.〔John Muir: ''Travels in Alaska''. Boston, New York, Houghton Mifflin co., 1915, p 45〕 Light-colored granite, about 50 to 70 million years old (Eocene Epoch to Cretaceous Period) has been sculpted by glaciers that gouged deep U-shaped troughs throughout the monument. Many of the glacial valleys are filled with sea water and are called "canals", but they are not man-made in any way; the walls of these valleys are near-vertical and often rise 2,000 to 3,000 feet (600 to 900 m) above sea level, and drop 1,000 feet (300 m) below it.
Across from the Salmon River and Portland Canal and the settlement of Hyder, Alaska, small glaciers occupy high areas of the northeast part of the monument. Soule and Through Glaciers cover high plateaus and valleys in the Lincoln and Seward Mountains, where one peak rises to 6,250 feet (1,900 m) above sea level. Most mountain tops in the monument are in the 4,000 to 5,000 foot (1,200 to 1,500 m) elevation range. Tree line is usually around 2,700 feet (800 m).
