A glacial boulder is a large rock that was transported by a glacier and deposited in a different location. These boulders can be massive, sometimes larger than a house. They are often composed of rock types that are different from the surrounding bedrock. Glacial boulders serve as evidence of past glacial activity, revealing how far glaciers once extended. Think of them as traveling rocks carried by icy rivers. These large rocks are a geological reminder of colder times.
The term 'glacial boulder' combines 'glacial,' relating to glaciers, and 'boulder,' referring to a large rock. 'Glacial' comes from the Latin word 'glacies,' meaning 'ice.'
