I was particularly interested in the question, after witnessing the performances of this San Joaquin band upon the glaciated rocks at the foot of the falls; and as soon as I procured specimens and examined their feet, all the mystery disappeared.

在目睹了这个圣华金乐队在瀑布脚下的冰川岩石上的表演后，我对这个问题特别感兴趣；一旦我获得了标本并检查了他们的脚，所有的谜团就消失了。

By the map I have come only about ten or twelve miles, though the sun is already low in the west, showing how long I must have lingered, observing, sketching, taking notes among the glaciated rocks and moraines and Alpine flower-beds.

根据地图，我只走了大约 10 或 12 英里， 虽然太阳已经落在西边， 这表明我在冰川形成的岩石、冰碛和阿尔卑斯花坛之间逗留、观察、素描、记笔记已经多长时间了。
