12 Sept 2009.
In preparation for a White Mountain Camping excursion, on the 12th of September, I set off to solo the most popular Franconia Ridge loop: Falling Waters Trail to Little Haystack Mt to Mt. Lincoln to Mt. Lafayette to Greenleaf Trail to the Old Bridle Path. The day was long, about eight and a half hours, but the visuals were stunning. 
The first waterfall on the Falling Waters Trail
Although rain pounded southern New Hampshire and Massachusetts, the skies were clear when I arrived at the White Mountains. However as I ascended Little Haystack Mountain, the clouds started to roll in. So much so, the view from the top of Little Haystack was less then picturesque.

After resting and eating at Little Haystack's summit, I decided to continue on to Lincoln. The last bit of Falling Waters was extremely steep and far more difficult than I expected. I was slightly concnered, if Falling Waters was the AMC's idea of an easy trail, I wasn't looking forward to meeting a "difficult" one.
I followed the trail blindly, the low clouds obscuring the mountains ahead, in near perfect silence occasionally interrupted by the sound of hiking poles striking rock and then voice.

The surrealism cannot be adequately explained. I was hiking on the most popular trail, seeing only 100 yards around, no other people, no sounds of people, silence only interrupted by the sounds I made. And then suddenly (and only occasionally) the dragging sound of hiking poles on rock, a voice or voices, and moments later a figure in the fog.
