The land must have been above the reach of the tide for the glacial drift to settle on it.
Difficult walking, all glacial drift, and boulders great and small.
In some lakes of the second class erosion undoubtedly entered into their formation as well as the piling up of glacial drift.
In the glaciated parts of the world, deposits of this nature have usually been removed and dispersed in the glacial drift.
Thus the stones, large and small, of glacial drift, will be smoothed and striated.
This theory has color given to it by the directions of movement shown by the glacial drift.
Much of the Triassic area is covered superficially by glacial drift and alluvium of the Trent.
Slates and fine-grained sandstones appear here freely through the glacial drift.
A good deal of the solid geology is obscured in many places by glacial drift, boulder clay and sands.
Often these lakes are without visible outlets, the water frequently percolating through the glacial drift.
