1970s Japan Air Lines "Alaska" poster, from a time when the stop in Anchorage on the way to the Lower 48 or Europe was so common in Japan that there was even a hit song about it. Photo taken at Portage Lake. Via SFO Museum

In early February 1979, Matanuska Valley schools were closed for at least 5 straight days due to high winds. I've grown tired of people who say AK schools never used to close in winter so I'm just starting to research it. Already have examples from a century ago.
