The same thing happens to this day, 【though on a smaller scale,】 【wherever a sediment-laden river or stream emerges from a mountain valley onto relatively flat land, dropping its load as the current slows: the water usually spreads out fanwise, depositing the sediment in the form of a smooth, fan-shaped slope. 】

翻译：现代也有冰水沉积，尽管规模相对较小。凡是有携带沙石的河流或者溪流从山谷流至相对平坦的地面时，砂石就随着水流速度的减慢逐渐沉淀；水流通畅呈扇形扩散，它们所携带的沙石也会沉淀为光滑的扇形斜面。
