This series comprises Eric Morse's trip files for his annual summer canoe trips between 1951 and 1980 and some shorter, local canoe trips. The files hold diaries and logs kept by the Morses or other members of the party; detailed notes on obstructions or portages; research notes on the journals of explorers or fur traders who had followed the same route; navigation plans, maps and charts; aerial photographs; snap shots of canoeists, campsites and scenic views; clippings of newspaper articles by or about the canoeists; licenses and permissions from the authorities; and correspondence and memoranda relating to the composition of the party, route chosen, logistics, catering, aircraft charters, and other arrangements. In addition to Morse's own trips, the series holds a map, flag, and mock-up of a "Toronto Sun" article about the 1985 expedition in his honour to the Morse River.
