The Last Glacial Maximum (LGM), also referred to as the Last Glacial Coldest Period, [1] was the most recent time during the Last Glacial Period where ice sheets were at their greatest extent 26,000 and 20,000 years ago. [2]
A chronology of climatic events of importance for the Last Glacial Period, about the last 120,000 years The Last Glacial Period caused a much lower global sea level.. The Last Glacial Period (LGP), also known as the Last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, c. 115,000 – c. 11,700 years ago, and thus corresponds to most of the ...
The Cordilleran ice sheet covered up to 1,500,000 square kilometres (580,000 sq mi) at the Last Glacial Maximum. [11] The eastern edge abutted the Laurentide ice sheet. The sheet was anchored in the Coast Mountains of British Columbia and Alberta, south into the Cascade Range of Washington. That is one and a half times the water held in the ...
The maximum ice extent occurred about 25,000–21,000 years ago during the last glacial maximum, also known as the Late Wisconsin in North America. The Last Glacial Period caused a much lower global sea level. This glaciation radically altered the geography north of the Ohio River, creating the Great Lakes.
The ice sheet covered up to 1,500,000 km 2 (580,000 sq mi) at the Last Glacial Maximum [2] and probably more than that in some previous periods, when it may have extended into the northeast extremity of Oregon and the Salmon River Mountains in Idaho.
Glacial history of Minnesota; Glacial period – Interval of time within an ice age that is marked by colder temperatures and glacier advances; Ice age – Period of long-term reduction in temperature of Earth's surface and atmosphere; Last Glacial Period – Period of major glaciations of the Northern Hemisphere (115,000–12,000 years ago)
During that time, the planet was in the grip of the Last Glacial Maximum, a period 19,000 to 26,000 years ago when two massive ice sheets covered the northern third of North America, reaching as ...
The Last Glacial Maximum extent was first reached 22 ka BP in the southern boundary of the ice sheet in Denmark, Germany and Western Poland (Sławskie Lake District and Leszczyńskie Lake District). In Eastern Poland, Lithuania, Belarus and Pskov Oblast in Russia the ice sheet reached its maximum extent about 19 ka BP.
