But that could change at any second in Keystone. With our altitude and the nature of Black Hills weather patterns, we are blessed with the occasional Chinook wind in the middle of winter.

How significant? Spearfish, to the north of Keystone, has held the world record for temperature change for more than seven decades. On the morning of Jan. 22, 1943, the temperature in Spearfish rose from -4 degrees to +45 degrees in just two minutes. That's a 49-degree change. Drivers had to stop in the middle of the street because their windshields suddenly frosted over.
