Misty Fjords National Monument

John Muir compared the area with Yosemite Valley for its similar geology and glacial morphology. 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 fjords 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. The tree line is usually around 2,700 feet (800 m). ==Ecology==

Western hemlock, Sitka spruce and western red cedar dominate the prolific rainforest vegetation; wildlife in abundance includes both grizzly and black bears, many species of salmon, whales, mountain goats, and Sitka black-tailed deer. ==Visitor access==

, have tiny islands that rise only a few feet above water level. Because of the remoteness of the area, most visitors arrive by boat or aircraft from Ketchikan or Juneau, Alaska. ==History==

The region was first visited by Europeans in 1793 when George Vancouver explored up Behm Canal, the prominent sea-filled glacial trough along the western margin of the monument and separating it from Revillagigedo Island. Vancouver discovered New Eddystone Rock, a 237-foot (72 m) tall column of basalt in the middle of Behm Canal. It was formed within the past 5 million years by volcanic activity, evidence for which is scattered sparsely through the monument, including a lava flow high above Punchbowl Cove, and at Blue River in the far northern part of the monument near the Canada–US border. ==See also==
