Mount Washington Summit Tower - New Hampshire, USA

This live webcam looks across Mount Washington’s rocky summit from the observatory tower in New Hampshire. Summit buildings, railings, and uneven boulders occupy the foreground, with successive mountain ridges extending toward the horizon. In colder conditions, thick ice coats exposed surfaces and can form striking shapes around the camera’s view.

The tower rises from the Sherman Adams Building within Mount Washington State Park. Its elevated position reveals the contrast between the developed summit and the surrounding mountain landscape. Clear skies expose distant ridgelines, while low clouds can sweep across the buildings and erase the background within minutes.

Weather shapes nearly every part of this scene. Snow settles between rocks, ice accumulates on structures, and changing light picks out details across the summit. The camera itself can occasionally become obstructed by ice, showing how directly these exposed surroundings are affected by freezing conditions.

Did You Know? Rime ice forms when supercooled liquid droplets in fog freeze on contact with surfaces, often building outward into the wind.
