Hundreds of hikers are heading up the summit of the Northeast's highest peak to raise money for the nonprofit Mount Washington Observatory. The annual "Seek the Peak'' fundraiser at Mount Washington is being held Saturday. The event has raised more than $1.3 million since 2001, helping the observatory maintain its famous weather station atop the summit. In 1934, observatory staff recorded a 231 mph gust that remains the highest wind speed ever observed by man. A remote sensor later recorded a 253 mph gust off Australia during a 1996 typhoon.
