The Four Mile Trail climbs the valley's southern wall to two of the park's great outlooks.

攀沿山谷南脊而上 将引领您直达公园内最超卓的两处观景点。

During the summer, the heat is trapped by the high valley walls and heated even more by the air pressure at its low point.

在夏天，热气被高高的谷坡困住并被谷底气压进一步加热。

July 18. Slept pretty well; the valley walls did not seem to fall, though I still fancied myself at the brink, alongside the white, plunging flood, especially when half asleep.

7月18日，睡得很好；山谷的墙壁似乎并没有倒塌，尽管我仍然幻想自己在边缘，在白色的、汹涌的洪水旁边，尤其是在半睡半醒的时候。
