The National Snow and Ice Data Center researches the cryosphere, and this website provides plenty of information on their work on the world of ice and snow. The Education Center homepage of their website will cause visitor's teeth to chatter just from looking at all the photos. There are several links to comprehensive discussions about Sea Ice, Snow, Frozen Ground, and Glaciers. One of those, called "All About Snow", has a link to an amazing "Gallery" of pictures of snow, such as the shocking photo of a 1966 blizzard in North Dakota that almost covered the utility poles, which is found in the "blizzards" section. Visitors should not miss the breath-taking photos of Sastrugi (wind-sculpted snow) in the "snow phenomena and formations" section of the gallery. Back on the homepage, visitors interested in a more condensed look at ice, should check out the "Quick Facts" link under "Basic Information" on the homepage, to find Quick Facts sections on "Arctic Sea Ice", "Ice Sheets", "Ice Shelves", and "Icebergs".
