Had a great time on this hike. Started out going through Franconia Notch where it was almost fog like. Very cloudy to begin. Parked at Seven Dwarfs for winter trailhead access. Adds an extra 1.5 miles each way. Little River was semi-raging and we had to go about a tenth of a mile beyond the third water crossing to find a safe ice bridge. North Twin trail is steep at the top, some unconsolidated snow made climbing difficult in spikes. Switched to snowshoes and it was much better. Once we emerged onto the rocks though, we were treated to a fantastic undercast with bright blue skies. It is one of the most astonishingly beautiful things to see. An ocean of clouds at your feet. There was Mt Wash, only its upper seen above the clouds. Not cold really, about 30 deg. As we made it to South Twin, the clouds were starting to dissipate. And a strong cold wind arrived too. South Twin has the best views in the Whites!
