Labor Day weekend several years ago, took my cousin's husband who is in his 50's. He had always wanted to hike MT W but living in PA had never gotten the chance. Hiked in some of the heaviest fog I have ever experienced in all my years growing up in, and now travelling home to, the Whites. Could not see hand in front of face.( Took a nice slider into a crevice on that rock slab as you are going up the Ammo too, surgically repaired knee was the leg that went right in. No injuries! Super slippery rocks) Once we got past Lakes then the wind started to hit us head on, cold and fast, as it came out of the north for a good ol' NWCO (North West Clear Off). By the time we summited, all clouds had blown off and we could see the Atlantic before we had to head down. That wind was biting and froze any moisture present into hoar-frost all over our clothes and faces. All that low pressure I swear gave me a ringing headache. It wasn't the worst weather I've experienced, I've certainly had worse on lesser peaks in the Whites.
Probably the most life threatning weather was a thunder-lightning storm that almost vaporized us on a Mt Jefferson hike in July 1989, fresh out of high school. Caps Ridge Trail. Never will forget that one. I remember the lightning hitting rocks above treeline and hearing it sizzle around as it sought out an outlet into the ground. That one really was a hair-raiser!
"LIVE FREE OR DIE...DEATH IS NOT THE WORST OF ALL EVILS." Gen. John Stark. "by reason of much foule weather and Extreme Bad Woods to travel in..." From the letter of my Great Uncle, Samuel Willard (accompanied by my grandfather Henry), to Governor Dummer on August 16, 1725, explaining the reason for his return, being instructed to "range all the country", of the Wawobadenik (White Mountains) July 19-August 16, 1725. I am a 13th generation New Englander and proud of it.
