话说看完露易丝湖的惊艳日出，众人决定一探露易丝湖的源头，大约20公里到达Plain of Six Glaciers，沿途有两个茶亭，汲取高山湖水配上大红袍。

露易丝湖水厚厚地奶蓝，往往若干落基山脉中的湖水展现不同平常的颜色，是由于冰山之粉（Rock flour, or glacial flour）的作用。

Rock flour, or glacial flour, consists of fine-grained, silt-sized particles of rock, generated by mechanical grinding of bedrock by glacial erosion or by artificial grinding to a similar size. Because the material is very small, it becomes suspended in meltwater making the water appear cloudy, which is sometimes known as glacial milk.[1][2]

一路顺着水声追寻，在高处看露易丝湖, 湖面就像一块绸缎，路过镜子湖，途经若干瀑布，水声潺潺，从石壁流下穿出，只能赞叹，语言再次显得苍白无力。
