The images in this collection were captured by Green Mountain Club members Theron S. Dean and Herbert Wheaton Congdon, both of whom were early contributors to the trail’s development. Congdon surveyed and mapped a large portion of the early trail including a fifty mile stretch from Middlebury Gap to Bolton. Congdon, along with Leroy Little and Clarence Cowles, is also credited with the first winter ascent of Mount Mansfield on February 21, 1920. Dean is perhaps the most prolific documenter of the Long Trail’s development. Dean travelled throughout Vermont presenting slideshows and giving talks about the Long Trail, often to hundreds of people.

A number of the original lantern slides in this collection were used by Congdon and Dean in their Long Trail presentations. Dean in particular meticulously cultivated his lantern slide collection and displayed these slides during his many talks. These lantern slides were originally digitized by the Landscape Change Program at the University of Vermont. The original slides can be viewed in the Dean and Congdon collections at the University of Vermont Special Collections in the Bailey Howe Library. More information about the Long Trail can be obtained from the Green Mountain Club.

The slides were scanned by UVM's Landscape Change Program with the generous support of the National Science Foundation. The digitized photographs also appear in the image database at http://www.uvm.edu/landscape/.
