Till samples were collected from approximately 160 sites in the Gaspé area, Québec.  No sampling year was given.  Samples were taken every 0.5 m depth to bedrock.  The density of sampling was greater if a facies changed occurred within the 0.5 m interval.  Sample weight varied between 0.5 – 1.5 kg.  A description of the study can be found in P. Bédard’s Université de Montréal Ph.D. Thesis.
