<h1>Glacier</h1> <Xpage=627>

<hw>Gla"cier</hw> <tt>(?)</tt>, <tt>n.</tt> <ety>[F. <ets>glacier</ets>, fr. <ets>glace</ets> ice, L. <ets>glacies</ets>.]</ety> <def>An immense field or stream of ice, formed in the region of perpetual snow, and moving slowly down a mountain slope or valley, as in the Alps, or over an extended area, as in Greenland.</def>

<note>&hand; The mass of compacted snow forming the upper part of a glacier is called the <i>firn</i>, or <i>n\'82v\'82</i>; the glacier proper consist of solid ice, deeply crevassed where broken up by irregularities in the slope or direction of its path. A glacier usually carries with it accumulations of stones and dirt called <i>moraines</i>, which are designated, according to their position, as <i>lateral</i>, <i>medial</i>, or <i>terminal</i> (see <er>Moraine</er>). The common rate of flow of the Alpine glaciers is from ten to twenty inches per day in summer, and about half that in winter.</note>

<cs><col>Glacier theory</col> <fld>(Geol.)</fld>, <cd>the theory that large parts of the frigid and temperate zones were covered with ice during the <i>glacial<i>, or <i>ice<i>, <i>period<i>, and that, by the agency of this ice, the loose materials on the earth's surface, called <i>drift<i> or <i>diluvium<i>, were transported and accumulated.</cd></cs>
