When these great ice sheets retreated, they left pulverized rocks in their wake, the foundation for fertile soil and some of the richest natural grasslands in America.
當這些大冰原消散,它們離開巖石,肥沃的土壤和一些最富饒的美國自然草原展現的一覽無余。
But in May this year, in the heart of Yellowstone, that grass is still beneath thick snow—something this ground squirrel was clearly not expecting.
但今年5月,在黃石國家公園的中心,草仍在厚重的雪下—這顯然不是地松鼠所希望的。
But as the sun's strength returns, spring bulbs start to push through the late snow—at last a sign that winter is losing its grip.
而隨著太陽強勢回歸,春天開始融化最后的雪—而最后一個跡象表明,冬天正失去其掌控。
Bluebirds, too delicate to survive deep winter here, now return to take advantage of the fist hatch of stone flies from the thawing river.
藍知更鳥,太過精致以致于不能在這深冬里生存,現在回來利用其身體獨特的優勢從解凍的河流中覓食。
