Should this item rank higher or lower?
–
Triple-storm-track 1,917 m New England peak where manned observers logged a 231 mph surface wind gust and relentless rime ice.
Sitting at just 1,917 meters (6,288 feet), Mount Washington lies at the convergence of Atlantic coastal, Gulf, and Pacific storm tracks. Funneling over the Presidential Range produced a manned-observatory 231 mph gust on April 12, 1934, using a custom heated Pitot-static anemometer.

- Rapidly plummeting barometer and 100+ mph gusts make winter traverses lethal without full alpine kit.
Eligibility
- Best for: Cold-weather gear testing and atmospheric icing research
- Cog railway and summer alpine ridge hikes
Things to Watch Out For
- Watch out for: Sub-freezing gales and whiteout fog strike even in July and August along exposed boulder fields
