Ice Age and Intraglacial Depression and Postglacial Rebound of Earth's Crust

This chapter aims to demonstrate of the real‐life practical, short‐term, ice engineering application of the special case of viscoelasticity, the “elasto–delayed‐elastic” concept. Earth's crust in central India became comparable to the ice sheet in Dow's Lake. The penetration of the lithospheric sheet into the mantle during the Ice Age was accommodated by the movement of the fluid mantle material away from the depressed areas. A relatively large section of the lake ice could easily be selected in the annual ice cover for our mini‐tectonic experiments related to postglacial rebounding. The occasion was the annual Winterlude festival's opening night concert in 1985 held for the first time on a pair of grandstands assembled on an ice sheet in the manu‐made Dow's Lake in the city of Ottawa, Canada. Floating ice sheets also exhibit elastic, delayed elastic, and viscous or permanent/residual deformation.
