snout of glacier

基本解释

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.
走到一処河灣，我們終於看到明永冰川這條巨龍的鼻尖：然而此処冰層的顔色死暗，其中混襍著石粉和灰土。
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.
這個冰川湖的一耑是冰川的末耑，另一耑則是一排由冰川搬運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，對冰川末耑縮退速度的測量衹是冰川變化的三種測量方法之一，另外兩種是冰川的“質量平衡”測算法和融水排放速度測算法。
