n. 堆石

moraine
n 1: accumulated earth and stones deposited by a glacier

Moraine \Mo*raine"\, n. [F. Cf. Prov. G. mur stones broken off,
It. mora a heap of stones, hillock, G. m["u]rbe soft, broken
up, OHG. muruwi, AS. mearu tender, Gr. ? to cause to wither,
Skr. ml[=a] to relax.] (Geol.)
An accumulation of earth and stones carried forward and
deposited by a glacier. --Lyell.
[1913 Webster]

Note: If the moraine is at the extremity of the glacier it is
a terminal moraine; if at the side, a lateral moraine;
if parallel to the side on the central portion of the
glacier, a medial moraine. See Illust. of {Glacier}. In
the last case it is formed by the union of the lateral
moraines of the branches of the glacier. A ground
moraine is one beneath the mass of ice.
[1913 Webster]
