8) Mount Washington
Mount Washington is the highest peak in the Northeastern United States at 6,288.2 ft (1,916.6 m) and the most topographically prominent mountain east of the Mississippi River.
The mountain is notorious for its erratic weather. This is partly due to the convergence of several storm tracks, mainly from the Atlantic to the south, the Gulf region, and the Pacific Northwest. On 12 April 1934, the Mount Washington Observatory recorded a windspeed of 231 miles per hour (372 km/h) at the summit. The mountain is located in the Presidential Range of the White Mountains, in Coös County, New Hampshire. The first regular meteorological observations on Mount Washington were conducted by the U.S. Signal Service, a precursor of the National Weather Service, from 1870 to 1892. The mountain is visited by hikers, and the Appalachian Trail crosses the summit.
