Overview

Excerpt from The American Geologist, Vol. 22 One may well ask why the spit began, and when it will end. I am not certain that I fully and clearly understand this point, though I see plainly that it is through no chance or accidental conditions that the spit develops. It has an explanation in the law, everywhere illustrated on coast lines, that waves sup plied with material will discover the easiest means of dis posing of it. In the case of Crowbar point the waves were, in the first place, driving materials both ways, the south winds pushing the pebbles toward the north and the north winds driving them in the reverse direction. There was a bend in the coast due to the projection of the old land; to this the waves from the south brought materials, but there they lost some of their power, and hence could not continue to carry all their load beyond the point, so some was dropped on the very point. The same was true of the waves from the north. They were able not merely to drive along the materials which they had wrested from the rocks, but also to turn back some of the debris which the south waves had driven beyond the point. But when these waves passed the point they lost their force likewise, and so both north and south-moving waves made this a dumping ground. As they built the spit out into the water, the interference of the point with the movement of materials to the north or south became greater and greater, until, at present, the spit forms an almost perfect barrier for the larger fragments. Had the south waves been greatly less powerful than those from the north, there would have been built a bar extending nearly parallel to the coast; but with nearly perfectly balanced waves from the two directions, the Spit must grow directly outward.
