Alluvial fan sediments contain valuable information on environmental change and anthropogenic influences, and function as an archive of landscape development. The purpose of this paper is to describe the analysis of the sedimentary information from core samples taken from two alluvial fans in the Saskatchewan prairies. The analysis assessed grain size, organic matter content, and microfossil presence to identify periods of accumulation and stabilization. Parker, Beavers, and Product weathering indices were used to analyze the modern source soil samples and the borehole cores to determine weathering/leaching conditions. The bed‐load transport sediments showed a higher leaching intensity whereas lower leaching was revealed for periods of stability, silt sheet flows, and sand sheet flows. The Beavers Index was not only a strong indicator of a bed‐load transport layer, but also of calcium accumulation zones marking alluvial fan surface stability. The large Dolomite/Calcite ratio marking the calcium accumulation zones was used for correlation between the two alluvial fan sites on a regional scale. A comparison of the stratigraphy of the two alluvial fans documents that a relationship exists between agriculture and an increase in erosion
