interglacial

It will be noted that I have indicated most separations as having taken place in interglacial ages.

Many of the valleys of our present rivers are but patchworks of preglacial, interglacial, and postglacial courses (Fig. 366).

The interglacial stages represent the 10,500 year periods when the earth in winter (northern hemisphere) is nearest the sun.

These gravels are exactly comparable to the interglacial gravels of the Sonthofen sections.
