unfissured

Ice caps are moving, dynamic masses which may fracture and heal giving the misleading impression that they have always been intact unfissured or unmelted, for example.

A fissured block of ice of this kind will be able to undergo a displacement at the two sides which form the crack, even when these continue to adhere in the unfissured part of the block.

Let us now enquire what proportion the area of these open fissures is likely to bear to the area of the unfissured crust.

If, instead of comparing the width of the fissures with the length of the lines of tension, we compared their areas with the area of the unfissured land, we should of course find the proportion much less.

The cols are simply depressions; in many of which the unfissured rock can be traced from side to side.

If we suppose the elevation to be due to the shrinking or subsidence of the land all round our assumed circle, we arrive equally at the conclusion that the area of the open fissures would be altogether insignificant as compared with that of the unfissured crust.

Now no examination of the bed of the river ever proved the existence of this fissure; and it is certain that water, particularly when charged with solid matter in suspension, can cut a channel through unfissured rock.

These considerations will help the imagination to realise what a small ratio the area of the open fissures must bear to the unfissured crust.
