Survey Description


Between 1981 and 1983, a total of 372 backhoe pits, ranging in depth between one and five metres were dug in three areas in southern Manitoba: the Balmoral – Komarno area, the Moosehorn – Gypsumville area and the Swan Lake – Dawson Bay area.  All the major lithosomes were sampled at least one in each area.  Till was sampled in every hole, but glaciolacustrine sediments were sampled in only a few places.  The backhoe pits were dug along road allowances and were variously spaced 0.25, 0.5 and 1 mile apart.  Each sample consisted of 25 kg collected for heavy mineral separation, 8 kg for textural analyses and pebble counts, and 0.5 kg collected for geochemistry.  The data are published in Manitoba Department of Energy and Mines GP 87-1.
