The Ice Age in the territory of present-day Latvia ended 14,000–12,000 years ago. The first human settlers arrived here during the Paleolithic Age 11,000–12,000 years ago. They were hunters, who following the reindeer herds camped along the rivers and shore of the Baltic Ice Lake .
With the exception of the coastal plains, the ice age divided Latvia into three main regions: the morainic Western and Eastern uplands and the Middle lowlands. Latvia holds over 12,000 rivers, only 17 of which are longer than 100 km (60 mi), and over 3,000 small lakes, most of which are eutrophic.
The Aiviekste is between 10,000 and 12,000 years old, formed at the end of the last ice age. Nearly a quarter of the river's flow is unregulated, but most of the river has been excavated, including with explosions. [2] The Aiviekste flows from the northern end of Lake Lubāns, where it does a wide semicircle and then turns southwest.
A less severe cold period or ice age is shown during the Jurassic-Cretaceous (150 Ma). There have been five or six major ice ages in the history of Earth over the past 3 billion years. The Late Cenozoic Ice Age began 34 million years ago, its latest phase being the Quaternary glaciation, in progress since 2.58 million years ago.
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 ...
What is probably the world's oldest ice, dating back 1.2m years ago, has been dug out from deep within Antarctica. Working at temperatures of -35C, a team of scientists extracted a 2.8km-long ...
Gutman's Cave (Latvian: Gūtmaņa ala) is the widest and highest cave in the Baltic countries, [1] located by the Gauja River in the area known as the ancient Gauja valley in the Gauja National Park near Sigulda, Latvia. It started forming more than 10,000 years ago when meltwater eroded the sandstone rock after the Ice Age.
Latvians maintained a considerable connection and trade with their neighbors. The first indications of human inhabitants on the lands of modern Latvia date archaeologically to c. 9000 BC, suggesting that the first settlers were hunters that stayed almost immediately following the end of the last ice age.
