Till sampling survey, NTS 62I, O, 63C, southern Manitoba, 1981-1983.
(requires an Internet connection)
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.

The geographic extent of the survey is defined by the following polygons:
Covers part of NTS 62I (Selkirk), the Balmoral - Komarno area in the southern Interlake, southern Manitoba. It is bounded to the northeast by Lake Winnipeg.
Covers part of NTS 62O (Dauphin Lake), the Moosehorn - Gypsumville area in the central Interlake, south central Manitoba. It is bounded to the west by Lake Manitoba.
Covers part of NTS 63C (Swan Lake), the Swan Lake – Dawson Bay area in the northern Westlake area, western Manitoba. It is bounded to the west by the Manitoba – Saskatchewan border.
