glacial ice
Compacted ancient snow
Glacial ice is ice that has formed from compacted snow over many years, dense enough to flow slowly under its own weight.
It makes up glaciers and ice sheets.
The term distinguishes this ancient, compressed ice from ordinary frozen water or seasonal ice formations.
The core sample revealed glacial ice thousands of years old.
