This project is aimed at understanding the relationship between glacial activity and sediment production, and at use of proglacial lake sediment sequences as indicators of upvalley glacial activity. Field work on the project has been undertaken in Banff and Jasper National Parks in Alberta and and Yoho National Park in British Columbia.
