[email protected]. Trowbridge: The Formation of Eskers THE FORMATION OF ESKERS. 211 -· THE FORMATION OF ESKERS. .ARTHUR C. TROWBRIDGE. Ever since work has been in progress in glaciated regions, long, nar -row, winding, steep-sided, conspicuous ridges of gravel and sand have been recognized by geologists. They are best developed and were first recognized as distinct phases of drift in Sweden, where they are called Osar. The term Osar has the priority over other terms, but in this country, probably for phonic reasons, the Irish term Esker has come into use. With apologies to Sweden, Esker will be used in the present paper. Other terms which have been applied to these ridges in various parts of the world are serpent-kames, serpentine kames, horsebacks, whalebacks, hogbacks, ridges, windrows, turnpikes, back furrows, ridge • furrows, morriners, and Indian roads .
