This has probably been mentioned here before: “Dartmouth by Air,” a video by the Media Production Group, is worth watching.
The red jeep visible alongside the Green in this postcard appears in a 1954 film. Bill Miles '56 notes in the comments that he played Freddy and that Bob Black '56 played Eddy in the film. The Alpha Delta house stands in for a dormitory in the serenade scene.
Rauner’s blog has several photos of skijoring at Carnival.
Transcripts of President Hopkins’s oral-history interviews from 1958 to 1964 are now available (see also Rauner blog).
Steve Waterhouse '65 has written A Passion for Skiing about Dartmouth’s contribution to the skiing industry (Vail Today).
