Started out of the Patterson Road Trailhead. It was a cold, but sunny day. The switchbacks to Prospect overlook added about half a mile more than the trail mileage online. The overlook had an amazing view of Williamstown and the valleys. Turned left towards Mount Williams, which had a few peaking views, and then through to Mount Fitch, which had no views at all (at least I couldn't find any). I turned back through Williams and back to the Overlook and then went out and back to Mount Prospect before heading back to the trailhead. The hike was a total of 11 miles. Some steep and icy parts at times, but not too difficult.
