Study uses changes in Hudson River may offer insight into how glaciers grew

Think of it like a geological mystery story: For decades, scientists have known that some 25,000 years ago, a massive ice sheet stretched to cover most of Canada and a large section of the northeastern United States, but what's been trickier to pin down is how—and especially how quickly—did it reach its ultimate size.

A graduate student working in the group of Jerry Mitrovica, the Frank B. Baird, Jr. Professor of Science, Pico is the lead author of a study that estimates how glaciers moved by examining how the weight of the ice sheet altered topography and led to changes in the course of the river. The study is described in a July 2018 paper published in Geology.
