An ice bridge is a frozen natural structure formed over seas, bays, rivers or lake surfaces. They facilitate migration of animals or people over a water body that was previously uncrossable by terrestrial animals, including humans. The most significant ice bridges are formed by glaciation, spanning distances of many miles over sometimes ...

The Perito Moreno (Spanish: Glaciar Perito Moreno), Francisco Gormaz or Bismarck Glacier [1] is a glacier located in Los Glaciares National Park in southwest Santa Cruz Province, Argentina, and originated in the Magallanes Region in Chile, being also part of the Bernardo O'Higgins National Park.

The famed Perito Moreno glacier ice bridge in Argentina’s Los Glaciares National Park fully collapsed in the early morning hours of March 12 after a glacial rupture began two days earlier.Park ...
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 ...
March 2017 became the sixth month in a row to set a record for the lowest sea ice extent, according to the National Snow and Ice Data Center (NSIDC). Operation Icebridge: NASA photos capture ...
It was not until 1974 that it could be completely closed by a 904 m long bridge. This is currently the longest bridge in Iceland. It was temporarily destroyed by water masses and blocks of ice during the last major glacial outburst flood in 1996, triggered by an eruption of the Grímsvötn volcano, but was immediately restored.
Arriving in North America south of glacial ice, they met naive prey under ecological stress. Emphasizing megafauna in their diet, these new arrivals added to that stress, increasing the ...
