The more I read about the Whites, I'm a little surprised how different they sound from the Adirondacks. It's like that additional 800' of elevation of the highest handful of peaks makes all the difference with long exposed ridges. In the Adirondacks you might get a mile of being exposed, but it dips back down into the trees pretty quickly. And a mile catches plenty of people off guard. I can think of two pretty serious but thankfully successful rescues because people got stuck above the treeline just in that short distance.
