Ice Sheet Retreat Of Up To 600m A Day Happened At End Of Last Ice Age Ice caps over the british isles at the end of the last ice age. these maps show the rate at which the ice sheet over the british isles during the last ice age melted. the ka on the images is short for thousand years and bp is "before present." so 27 ka bp is the map of the ice sheet at 27 000 years ago.

Subsequent research has confirmed that the "ice age floods" were among the greatest such events in the known history of the planet. in the okanogan highlands and north cascades, the retreating ice sheet left moraines and drumlins scattered across the landscape. moraines are large hills of rock and sediment carried by ice and deposited as it melts. New york’s glacial landscape. new york city marks the southernmost boundary of an ice sheet that mantled much of north america, advancing and retreating over a period of around 90,000 years. the last glacial advance of the wisconsin ice sheet reached new york city between 22,000 and 20,000 years ago. ice covered manhattan island and the upper.
