   where $\rhom$ is the density of the mantle and $\rhoi$ is the density of the ice.
   Following the melting of an ice sheet (deglaciation), the crust begins to rebound in a process known as isostatic uplift or post-glacial rebound. The rate of this rebound is constrained by the viscosity of the upper mantle. In regions once covered by the [Laurentide Ice Sheet](/entries/laurentide-ice-sheet…

2. Isostatic Rebound

   Glacial Loading and Unloading Cycles
   The most dramatic and studied examples of isostatic rebound are associated with the Pleistocene ice sheets. During glacial maxima, the immense weight of kilometers-thick ice depressed the crust, creating significant gravitational potential energy stored in the mantle. Following deglaciation (ablation), the removal of this load initiated the rebound.
   The rate of uplift is not linear. Initial vertical movement immediately post-loa…
