A day-and-a-half of rain together with the large numbers of hikers this weekend turned the Marcy Dam trail into a series of quagmires with sporadic dry patches in between. The trail from Marcy Dam up to the cairn was OK, but the path beyond the cairn was a muddy ditch. There's a short stretch in the middle with sloping bedrock and easy walking even with lots of water runnig down it, but from the heighth of land to the true summit was very sloppy. Cripplebrush hampers attempts to skirt the deep mud. Rain turned to snow at the top, but sun & blue skies by the time we got back to Marcy Dam.
