Popis:	Soil stratigraphical and pedological techniques were used to examine the evolution of paleosols in the Highwood River Basin of southern Alberta. The paleosols were located on three types of glacial deposits: glacio-lacustrine, glacio-fluvial, and diamicton. Before the deposition of Mazama tephra at 6600 year B.P. (prior to 6600 years B.P.) episodic colluviation occurred on sloping sites, with paleosols forming during depositional hiatuses. Level surfaces were stable, allowing formation of thick, well-developed paleosols. Eolian deposition occurred on all surfaces during the last 6600 yr. The morphological and analytical characteristics of the paleosols differ depending on the influence of topography on the geomorphic processes occurring at the site. The variability in paleosols in this area limits the type of paleoenvironment information which can be inferred from paleosols. Key words: Holocene soil, paleosol, soil genesis, landscape position, soil geomorphology
