Abstract
Five occurrences of the Prelate Ferry paleosol are known in exposures in the tributaries of the South Saskatchewan Valley between the Prelate Ferry and Lancer Ferry crossings, in Saskatchewan. At the reference section, 8 mi north of Prelate, Saskatchewan, the paleosol is best developed, and comprises a very dark brown A1b horizon, 12 in. thick; a grey A2b horizon, 7 in.; a dark brown B1b and a lighter B2b horizon, 12 and 19 in. thick respectively and a Cb horizon, more than 10 in. thick. The paleosol, a planosol or possibly a solodized-solonetz, developed on the lower till and is buried by 120 ft of sediments comprising two till sheets and three beds of stratified drift. The non-gIacial Prelate Ferry interval during which the paleosol formed had a local climate similar to that of today. The beginning of the interval is not known, but it ended about 20 000 years ago, when the last major ice advance occurred in the area. Laboratory examinations indicate that the paleosol is pollen-sterile; it shows an upward decrease in grain size; it is weathered, noncalcareous in most parts; it is slightly to strongly alkaline; andit has a clay mineral content similar to that of the underlying till.
