snout of glacier

基本解釋

Around a bend in the river, the glacier's snout finally comes into view: It's a deathly shade of black, permeated with pulverized rock and dirt.
走到一處河灣，我們終于看到明永冰川這條巨龍的鼻尖：然而此處冰層的顏色死暗，其中混雜著石粉和灰土。
This glacial lake is bound by the glacier snout on one end, and a moraine—a mound formed by the accumulation of sediments and rocks moved by the glacier—on the other.
這個(gè)冰川湖的一端是冰川的末端，另一端則是一排由冰川搬運(yùn)來的沉積物和巖石累積而成的冰磧。
But, the retreat of a glacier’s “snout” is only one of three measures of how glaciers can change. The other two are its “mass balance” and the rate at which melt-water is discharged.
但是，對(duì)冰川末端縮退速度的測(cè)量只是冰川變化的三種測(cè)量方法之一，另外兩種是冰川的“質(zhì)量平衡”測(cè)算法和融水排放速度測(cè)算法。
