話說看完露易絲湖的驚艷日出，眾人決定一探露易絲湖的源頭，大約20公里到達Plain of Six Glaciers，沿途有兩個茶亭，汲取高山湖水配上大紅袍。

露易絲湖水厚厚地奶藍，往往若乾落基山脈中的湖水展現不同平常的顏色，是由於冰山之粉（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]

一路順着水聲追尋，在高處看露易絲湖, 湖面就像一塊綢緞，路過鏡子湖，途經若干瀑布，水聲潺潺，從石壁流下穿出，只能讚嘆，語言再次顯得蒼白無力。
