Narrows

Definition and stakes

Portrait of Lydia Huntley Sigourney Lydia Huntley Sigourney,  Scenes in my Native Land (1845)

“ The perpetual gliding of sails, and the rapid movement of steamers, brilliant with their evening lights, give to the prospect of the surrounding sea continual variety and interest. The Narrows, that watery pathway, through which the voyager to distant climes passes, his heart broken with the tender farewells of beloved ones, and by which he returns, in joy unutterable, every thought filled to overflowing with the imagery of home and native land, can never be viewed with indifference by those who have felt these emotions. ”

“ Narrows.—Where a stream crosses a hard layer or ridge of rock lying between softer ones, the valley will not widen so rapidly in the hard rock as above and below. If the hard beds be vertical, so that their outcrop is not shifted as the degradation of the surface proceeds, a notable constriction of the valley results. Such a constriction is a narrows. The Upper and Lower narrows of the Baraboo (Plate IV) are good examples of the effect of hard rock on the widening of a valley. ”

Portrait of Thomas C. Chamberlin Thomas C. Chamberlin,  Geology (1906)

“ Narrows are much more conspicuous in certain stages of erosion than in others. While a valley is still so young as to be narrow at142 all points, no narrows will be conspicuous; but at a later stage in its history, when the valley is otherwise wide, narrows are more pronounced. At a still later stage, when the hard strata themselves approach base-level, the narrows again become inconspicuous. ”
