Marcy II Expedition (aka Bill & Henry's Excellent Adventure) 2008 The Facts: Henry and I summited Marcy at 11:30 am on March 10, beautiful clear skies but good adventure with 80 mph winds and treacherous footing on the icy top; at 2:20 we summited Tabletop, another nearby high peak--and that is a twisted gnarly trail tale unto itself.
