This week is peak season for fall color in the White Mountains of New Hampshire. We’ve watched the colors spread and intensify in the few days we’ve been here. The annual fall show is expected to reach its climax this weekend but Thursday morning’s spectacular showing at Willey House on the Saco River was like nothing I’d ever seen. The rich hues, especially the many nuances of reds and oranges with some magenta and yellows competing for attention, is an unforgettable palette of colors that creates a vibrant display across the hillsides.
