The main bulk of the files are survey records. These document stations occupied, data, bearings, field sketches, and often include catalogues of specimens, localities, and photographs. These were written on 8x10” paper.
The series also includes field notebooks (approx. 500) kept by each member of the party. They document occupied stations, observed points (triangular), specimens collected, and those locations/specimens which were photographed. Brian Harland explained in a number of expedition bulletins, that these field notes would form the basis of the survey records.
Log books record the times and dates of stopping and starting, compass bearings, include sketch maps, gradients of snow surfaces, the number of photographs or specimens taken, and include weather records.
Photograph albums (often) include indexes/contents lists. They depict personnel, accommodation, food, specimens, panoramas, and wildlife.
The series also includes loose letters, maps, and ephemera.
