description Saint-Mathieu Esker Overview
Saint-Mathieu Esker, also called the Saint-Mathieu-Berry esker, is a fluvioglacial sedimentary ridge and aquifer system in Abitibi, Quebec. Its permeable sands, gravels, cobbles, and locally confined sediments store and transmit groundwater; the wider esker extends about 120 kilometres and supplies wells in the Amos area. It is studied in geology, hydrogeology, groundwater protection, and aggregate-management contexts.

How does the Saint-Mathieu Esker act as an aquifer?
Its permeable sands, gravels, and cobbles allow groundwater to move through the esker. Locally confined sediments can also store water below less-permeable layers.
How long is the Saint-Mathieu-Berry esker?
The wider esker extends for about 120 kilometres. It crosses the Abitibi region as both a sedimentary landform and groundwater system.
Why is the Saint-Mathieu Esker important?
