Evidence of widespread glaciation of Amund Ringnes Island includes: northwestward-striking grooves and striations in bedrock at three widely separated localities and at elevations of about 60 m, 150 m, and 230 m; and abundant striated erratics, including granite and gneissic rocks. Isolated, sinuous deposits of boulder gravel may be eskers. Dated barnacle shells at approximately 30 m and 35 m above sea level indicate that significant rebound has occurred in the last 8000 to 8500 years, following removal of the ice load.A cluster of small, but well-developed pingos lies on a nearly flat, featureless plain in the central part of the island.
