=Kames.=—Within reëntrants or recesses of the ice margin the drift deposits were especially heavy, so that high hills of hummocky surface have been built up, which are described as _kames_. Most of the higher drift hills have this origin. They rarely have any principal extension along a single direction, but are composed in large part of assorted materials. In contrast with other portions of the morainal ridges they lack the prominent basins known as kettles. Other _kames_ are high hills of assorted materials not in direct association with moraines and believed to have been built up beneath glacier wells or mills (p. 278). =Outwash plains.=—Upon the outer margin of the moraine is generally to be found a plain of glacial “outwash” composed of sand or gravel deposited by the braided streams (Fig. 308, p. 280) flowing from the glacier margin. Such plains, while notably flat (Fig. 338), slope gently away from the moraine. Between the outwash plain and the moraine there is sometimes found a pit, or _fosse_ (Fig. 309, p. 281), where a part of the ice front was in part buried in its own outwash (Fig. 339). [Illustration: FIG. 340.—View looking along an esker in southern Maine (after Stone).] =Pitted plains and interlobate moraines.=—Where glacial outwash is concentrated within a long and narrow reëntrant, separating glacial lobes, strips of high plain are sometimes built up which overtop the other glacial deposits of the district. The sand and gravel which compose such plains have a surface which is pitted by numerous deep and more or less circular lakes, so that the term “pitted plain” has been applied to them. The surface of such a plain steadily rises toward its highest point in the angle between the ice lobes. Though consisting almost entirely of assorted materials, and built up largely without the ice margins, such gently sloping pitted platforms are described as _interlobate moraines_. Upon a topographic map the course of such an interlobate moraine may often be followed by the belts of small pit lakes (see Fig. 336). [Illustration: FIG. 341.—Outline map showing the eskers of Finland trending southeasterly toward the festooned moraines at the margin of the ice. The characteristic lakes of a glaciated region appear behind the moraines (after J. J. Sederholm).] [Illustration: FIG. 342.—Small sketch maps showing the relationships in size, proportions, and orientation of drumlins and eskers in southern Wisconsin. The eskers are in solid black (after Alden).]
