Pleistocene epoch.
The Pleistocene (about 2.58 million to 11,700 years ago) is the well-known recent Ice Age with repeated glacial advances and retreats. (Earth also experienced earlier ice ages — e.g., the Late Paleozoic glaciation — but the Holocene is a current interglacial and the Archaean is not when the main Ice Ages occurred.)
