Short summary

Understanding past ice sheet behaviours is key to predicting future ice sheets in a warming climate, but meshing geological observations with ice sheet models is challenging. This manuscript models the sedimentary system of the Finnish Lake District Ice Lobe during its retreat about 12 000 years ago, when extensive water flow developed under the ice, and connects models with observations. The approach opens a path to improve knowledge of previously glaciated regions and systems under ice today.
