The Wisconsin Glacier was ploughing logs into the terminal moraine in Miami lobe as far back as about 19,500 yr ago (W-304 Westchester and W-724 or W-738 Hamilton) whereas the ice of Scioto lobe emplaced logs in end moraine 18,100 yr ago (Y-448 Cuba, W-91 Chillicothe, W-331 Anderson).
This was recognized by the earliest workers (Chamberlain 1882) from the outlines of terminal moraines (Fig.
Elias Mountains, based on tree-ring dating of white spruce, Picea glauca (Moench) Voss, that were killed during construction of the outermost terminal moraine.
2, 3) on the distal side of the outermost terminal moraine.
We obtained a tree-ring kill date of AD 1717 on a tilted spruce snag (02-28-1) east of the bedrock hill, on the distal side of the outermost terminal moraine bordering the east lobe of Kaskawulsh Glacier (Fig.
Key words: alpine glacier, Axel Heiberg Island, terminal moraine, advance, retreat, climate
Ice appears to override the terminal moraine in both cases.
Magnificently showcasing the effects of continental glaciation (in some places the flow of glacial ice was as much as two miles deep) created a variety of geologic features including kames, kettles, drumlins, ice-walled-lake plans, eskers, tunnel channels, basalt bluffs, dells, and rock-strewn terminal moraines
First, Wegener's famous map showing the supposed arrangement of land during the geologically recent Pleistocene where the outer terminal moraines
of the ice sheets in Europe and North America 'join up smoothly' was patently incorrect and quickly rejected.
The company is busy, the order book is full, production lines are churning the stuff out and the cleaning room looks like the terminal moraines
of a glacier--plugged, blocked, choked and full to the roof.
Ages of glacier advances can be estimated by dating plant remains in lateral and terminal moraines
, or by determining the age of trees or lichens growing on the moraines (Fig.
