Lake Arnold sucked for me too. I was stuck in a three day rain and sleet storm that forced me to cut my plans short from climbing Mt. Marcy and other mountains. The view from Mt. Colden was excellent, but the view from the nearby false summit was even more impressive. The best part in an otherwise disasterous trip.
Amazing expierence. Totaly out of this world. Only complantent was being laughed at by several DEC employees at the Noonmark Diner when we told them we were doing the dike. Also, my dad (who dosent rock climb) didn't have the greatest time on the waterfall.
