Overview

Excerpt from The Geology of Long Island: From the Annals of the New York Academy of Sciences, Vol. III, Nos. 11 and 12, 1886 Astoria to Orient Point. These two ranges of hills are the re sult of glacial action, and the more southern chain marks the southern limit of the drift. Upham and others, in speaking of these ranges, have called them moraines. If the word moraine is to be thus used, and present custom in the United States appears to sanction the use, it must be taken in a different sense from that accorded to it in most regions of glacial action. In Switzerland and other moun tainous countries, the term is applied to great accumulations of boulders and rock detritus, piled up along the sides or front of a glacier. Throughout most of Long Island and at many points on the New England coast, however, the thickness of the drift on the ridges marking the southern limit of glacial extension is very slight and in some cases it is wanting. In these cases, the term moraine would be synonymous with the southern limit of the Continental glacier. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
