A rather famous place here in the North-East USA. The weather there, at the summit (6288 feet or 1916 m), is some of the worst on Earth. There's been a deep cold snap here, and looking at the weather station report just before I awoke at 415AM shows the following...
020423 0349EST -47F Wind NW 89-97 mph Freezing Fog, Blwing Snow, and Windy
Wind Chill -108F
BTW: a Mercury thermometer would freeze and be as hard as steel at those factors.
My local news TV station (Ch 3 Hartford, CT) actually showed video of the site and pronounced it a record low wind chill and tied the low temp (1932).
Around here a balmy -5F with 25-35mph wind... about -20F.
