Huronian

The Huronian glaciation extended from 2400 mya to 2100 mya, during the Siderian and Rhyacian periods of the Paleoproterozoic era. It was one of the most severe ice ages in geologic history and some geologists believe that it was very similar to the Snowball earth ice age that happened in the neoproterozoic era.

glacier is a large, slow moving river of ice, formed from compacted layers of snow, that slowly deforms and flows in response to gravity. Glacier ice is the largest reservoir of fresh water on Earth, and second only to oceans as the largest reservoir of total water.

mya or "m.y.a." is an abbreviation for million years ago. This abbreviation is commonly used as a unit of time to denote length of time before the present or "B.P." (before AD 1950). Specifically, one mya is equal to 106 years ago.

The Neoproterozoic Era is the unit of geologic time from 1,000 to 542 +/- 0.3 million years ago.[1] The terminal Era of the formal Proterozoic Eon (or the informal "Precambrian"), it is further subdivided into the Tonian, Cryogenian, and Ediacaran Periods.

Proterozoic (IPA: /ˌprəʊt(ə)rəˈzəʊɪk/) is a geological eon representing a period before the first abundant complex life on Earth. The Proterozoic Eon extended from 2500 Ma to 542.

The Mesoproterozoic Era is a geologic era that occurred between 1600 Ma and 1000 Ma (million years ago).

The major events of this era are the formation of the Rodinia supercontinent, the breakup of the Columbia supercontinent, and the evolution of sexual reproduction.

The Calymmian (from Greek calymma, "cover") is the first geologic period in the Mesoproterozoic Era and lasted from 1600 Ma to 1400 Ma (million years ago). Instead of being based on stratigraphy, these dates are defined chronometrically.

The Tonian (from Greek tonas, "stretch") is the first geologic period in the Neoproterozoic Era and lasted from 1000 Ma to 850 Ma (million years ago). Instead of being based on stratigraphy, these dates are defined by the ICS based on radiometric chronometry.
