While doing some research on and area in the Whites I stumbled onto the Daniel Doan Collection at dartmouth over the net. The collection is divided up into boxes and then folders - Titled by their contents (photos of Mt. .... or notes on hike to ......). The staff at Dartmouth College Library were very nice and helpful. They mailed me copies of some photos and notes I wanted to see. There is a cost for some shipping and color copying or they maybe able to scan and email. If you go through the table of contents - via the link below (scroll down when you get to the site) you will see there are a lot of topics that maybe of interest to you. Just an FYI I had been meaning to post.
