AB - From 18,000 to 6500 years ago the ice sheets covering North America melted, and sea level rose almost 100 meters. Since that time, sea level has remained almost constant, but the earth has not yet completed its adjustment to the removal of the ice load. In the center of the uplifted region the ground has risen 138 meters in the last 6000 years and is rising at a rate of 2 ± 0.5 cm/yr today; there may be another 300 ± 120 meters of vertical motion left before isostatic equilibrium is reached. This review collects the evidence of vertical movements in northern and eastern North America from different sources and disciplines to provide in one publication the quantitative data important for geophysical analyses of glacio‐isostatic rebound. The paper covers evidence from the area of uplift and the peripheral zone of submergence and from the past movements and instrumentally recorded recent trends, provides a discussion of the eustatic rise in sea level, and gives an updated free‐air gravity anomaly map of the deglaciated region.
