Abstract
Ice-push action causes considerable shore and vegetation damage on lakes located 10–40 km southeast of Schefferville in central Quebec – Labrador. The damage occurs mainly on shores of large lakes; on small ones the damage is slight. In the spring the wind-driven ice thrusting up on the shores moves shore material, even quite large stones, and forms fine ice-push ridges. It also uproots trees and shifts them far landward. The ice-made features on shores of large lakes are common: they occur on 46% of the shores. In addition, there is slight vegetation damage on 32% of the shores; only 22% of the shores lack signs of ice push. Ice push is a major process moulding the shorelines of these lakes.
