a.       The Mount Washington Observatory’s mountaintop weather station has been staffed continuously since it’s founding in 1932. It is operated by two alternating crews of Observers who live on the summit for a week at a time taking hourly weather observations around the clock, performing research, producing higher summits forecasts, and conducting educational programs. Each shift is comprised on two day observers and one night observer ensuring around the clock attention.

6.       What makes Mount Washington’s weather so extreme especially for a small peak compared to other North American Mountains?

a.       Height: Mount Washington is the highest peak in the Northeast allowing for little to no obstruction of winds as they reach the summit.

b.       Storm Tracks: The Northeast is a frequently stormy area in general, with a new storms moving through the area every 3 days on average.
