Scientific men perceived in it a confirmation of their theories concerning the glacial period
; so through their persuasions the little tract of ground was bought and permanently protected against being built upon.
The scientific celebrities, forgetting their mollusks and glacial periods
, gossiped about art, while devoting themselves to oysters and ices with characteristic energy; the young musician, who was charming the city like a second Orpheus, talked horses; and the specimen of the British nobility present happened to be the most ordinary man of the party.
Over a comparatively short span of time, mountain glaciers of the last major glacial period
shape skyline in this mountainous park.
* On many land surfaces, the crust has been elevated by mountain-building tectonic forces, while part of Earth's surface is still rising due to loss of the weight of glacial shields that covered a great deal of land during the last glacial period
During the last glacial period
, around 12,000 to 110,000 years ago, woolly mammoths, sedan-sized armadillos and other massive mammals walked the land.
Additionally, climate scientists may better understand the chains of events that led to the advance and retreat of the ice sheets during the last glacial period
David Montgomery of the University of Washington and a colleague used topographic data taken from laser-based measurements to determine that, if the gorges were indeed erased during each glacial episode, the rivers would then have had to erode the bed rock at a rate of 0.8-2 centimetres per year since the last glacial period
in order to create gorges as deep as those present today.
For the Magdalenian hunters did not confine themselves, as their forefathers had, to making utilitarian tools to enable them to fulfil their most basic needs, such as finding food, defending themselves from pillagers, and protecting themselves from the hostile cold in a Europe in the throes of the last great glacial period
. They were also responsible for works of artistic expression, which strike us as impressive even today, despite the fact that their culture was so different, that many millennia separate us from them, and we find it difficult to grasp the full significance of the paintings, engravings and sculptures in the caves or of the small objects that they sculpted and decorated, so characteristic of their culture.
At the height of the last glacial period
18 000 years ago, the mountain pigmy possum, Burramys parvus, ranged widely across the frigid high country of south-eastern Australia.
"The discovery of this mammoth skull increases the probability that there were at least two migrations of Columbian mammoths to the island - during the most recent ice age 10-30,000 years ago, as well as the previous glacial period
that occurred about 150,000 years ago." USGS geologist Dan Muhs said.
