Topping out at 6,288 feet above sea level, Mount Washington, New Hampshire, located some 130 miles north of Boston, is the highest point in the northeastern United States.
Here are five facts about Mount Washington:
* The Mount Washington Observatory has been staffed continuously since 1932, with the exception of a brief evacuation in February 2004 due to a fire.
* In April 1934, the observatory recorded a 231-mile-per-hour (372 kmh) wind that remains a world record for a land-based weather station. Some of the observatory buildings are secured to the summit with chains to keep them from blowing away. Temperatures atop the mountain can drop as low as -47 degrees Fahrenheit (-44 C)
* The average temperature on the summit is 26.5 degrees Fahrenheit (-3 C), winds average 35.3 miles per hour (56.8 kmh). The summit gets about 42 feet of snow per year, and typically sees snowfall every month of the year -- though it melts quickly in the summer.
* Summit staff work 12-hour shifts in eight-day cycles. Typically shifts change on Wednesday, although severe weather conditions sometimes force a change. They do not shower while working atop the mountain.
* On the clearest days, observers can see as far as Mount Marcy in New York State, 134 miles to the west.
