You'v got it.. Mt McKinley=Denali=Highest peak in North America...(somewhere in Alaska)

Mt Washington, NH, (don't know its previous name) highest peak on east coast, also vies for worst weather in the world.. but that's because the US Weather service has a station there, so its weather is well documented.

the only time i was at the top of Mt Washington (mid July) we got caught in a snowstorm, with a white out condition. you couldn't see 10 feet ahead! we took the cog railrail (i wanted to drive!) and only found the train because it blew the whistle-- we couldn't see it until we were practically on it! it was 90°F., at base (35° c. or about)and 35°F (1°c) at the top!
