Despite the outsized-seeming boast that this otherwise unassuming peak is "Home of the World's Worst Weather," unwary visitors every year learn the hard way that Mount Washington is certainly a contender for that title. Take the fact that even when it's a sunny hot day in the area, shorts-wearing explorers will discover that the summit is likely freezing: on average it's a frigid 27 degrees, and the thermometer has never even ventured above 72. As a result more than a hundred climbers have succumbed over the years from any manner of weather-related mishaps, from exposure, avalanche, or being blown off a cliff (the mountain also holds the wind-speed record of 231 mph).
