Multi-year till sampling surveys, province of Alberta, 1953-1968.
(requires an Internet connection)
Approximately 475 till samples were collected from over 65% of the province of Alberta during 1958-1963. Sampling was carried out over areas covered by the continental Keewatin ice sheet. The unsampled areas were covered by drift from the Rocky Mountains (i.e. along southwestern margin of the province), were difficult to access or were covered by deposits other than till, as in northern Alberta where large areas are covered by lacustrine sediments. Some samples were collected by Alberta Soil Survey staff during the course of their fieldwork. A summary of the work is published in CJES v.4 and in Research Council of Alberta Bulletin 26.
Fraction not stated; analyses of Cu, B, and Cu by a rapid powder-spark technique, using an emission spectrograph. Fe, Mn, and Ca by XRF; Zn and Mo by a DC arc rack-up technique.

The geographic extent of the survey is defined by the following polygons:
Covers 65% of the province of Alberta and represents the areas affected by the continental Keewatin ice sheet. A small portion in the southwest and some parts of the northeast and northwest are excluded from the study area.
