Recent high-resolution LiDAR (Light Detection and Ranging) images of Anticosti Island (Québec, Canada) have revealed novel landforms created by glacial erosion that strongly nuance the previously published understanding of its glacial history. These diverse forms of glacial erosion include feature carved into the bedrock, such as glacially overdeepened lakes, rock drumlins, giant grooves, and mega crag-and-tails, as well as slabs of rock displaced by glaciers. Although mostly relatively inconspicuous, these forms of glacial erosion are present throughout the island. However, the glacial imprint is strongest in the eastern and western lowlands. In the eastern lowlands, the southwestward ice flow that occurred everywhere on the island was followed by a southeastward flow. Both these flows originated on the Canadian Shield (Laurentide Ice Sheet). Indicators of a late northward flow were observed in the northern half of the central plateau (north of the Jupiter River). This northward flow is attributed to the regional ice cap that occupied the central plateau during deglaciation.
