Limbs perfectly tireless until near sundown, when I descended into the main upper Tuolumne valley at the foot of Mount Lyell, the camp still eight or ten miles distant.

四肢完全不知疲倦，直到接近日落时，我才下到莱尔山脚下的图奥勒米上游主要山谷，距离营地还有八到十英里。

Tracing the river, we find that it forks a mile above the Soda Springs, the main fork turning southward to Mount Lyell, the other eastward to Mount Dana and Mount Gibbs.

沿着这条河， 我们发现它在 Soda Springs 上方一英里处分叉， 主分叉向南转向莱尔山， 另一个向东转向达纳山和吉布斯山。

The upper end of the series lies at the base of Mount Lyell, the lower below the east end of the Hoffman Range, so the length must be about ten or twelve miles.

该系列的上端位于莱尔山脚下，下端位于霍夫曼山脉东端下方，因此长度大约为 10 或 12 英里。
