For high southern latitudes special value in the American method was useless for this purpose.
In intermediate latitudes there is a loss of heat and then the increased density due to equatorial concentration becomes a factor.
Russia the summer is much warmer than in the corresponding latitudes of France, and really hot weather is.
Shore Deposits are the product of the waste of the land arranged and bedded by the action of currents or tidal streams. On the rocky coast of high latitudes blocks of stone detached by frost fall on the beach and becoming embedded in ice during winter are often drifted out to sea and so carry the shore deposits to some distance from the land.
There will be great outbursts of polar ice, but this will melt at higher latitudes than in the periods when the tide-generating force is minimal.
