Poorly stratified deposits of coarse gravel cover Kennedy Ridge and several other planation surfaces east of Glacier National Park in north-central Montana, U.S.A., and adjacent Alberta, Canada. These gravel deposits, commonly called "Kennedy drift" and classified as glacial drift, are composed primarily of lithologies identical to Belt Supergroup rocks observed in the Rocky Mountains immediately to the west. In recent years, the Kennedy gravel has been described as a series of tills containing paleosols documenting several glacial and interglacial episodes over the course of approximately two million years. Fabric measurements and paleomagnetic surveys have been taken and the evidence interpreted in support of the multiple till interpretation. However, these data are far from unequivocal, and alternative genetic interpretations may be superior to the multiple till interpretation.
