Description :
In the research area, the earliest sediments deposited in the larger lakes predate European settlement, allowing direct evaluation of basin response to settlement. Pre- and post-settlement sediments in a central core were separated on the basis of an increase in Populus pollen associated with the southward advance of the aspen parkland ecotone caused by fire suppression following settlement. This study focuses on sediment characteristics. At present, topsoil is the dominant suspended sediment source in small drainage basins in the field area. The aim of this paper was to investigate whether this has always been the case.
