回复：谢谢你的资讯，这两天忙着写帖子， 一直没回你的短信。

Q: 你说的这个水源是不是和你在短信里说的那个， 是同一个？
A: Yes.

Q: 在Small Yosemite 里?
A: No. Sorry for the confusing. It is not in but over Little Yosemite. It is infact over Cloud Rest(?), the last fork in the trail map you posted.

Q: 那你这次带了多少水？ 我指一个人.
A: For me, total consumption: about 7 bottles, 500ml/bottle.
(1) Start: 3-4 bottles
(2) Top off on the way up: all bottles in the last water source, since water purification pill I used takes time to take effect.
(3) Leave: 1 bottle on the way up to the cable trail, just did not like to carry it up and down all the way.
(4) Refill on the way down: 1-2 bottles.

I think I consumed more water than average. However, if it is hot, like around 33C, than more water is needed.

Q: 还有， 我觉得Mist Trail不是非常难走， 对我来讲， 我也没觉得累， 剩下的那个7-mile的路你觉得比这难， 还是容易？
A:
The trail itself is in very good condition, except these close to the top of Nevada Fall.

Four big hurdles/steep stairs on the way to the top of Half Dome: (A) up to Vernal Falls, (B) up to Nevada Falls, (C) to Top of the bulge right before Half Dome, (D) and the Cable Trail. In my opinion, the order of difficulty is: (C), (D), (A) and (B).

Up Mist Trail is just one fourth of the effort, hiking just starts and we get the cool mist. (C) is the most difficult one because we get wore out when we reach it. It is also very steep and without the help of cable. Don’t worry about how to get down the steep slope when you are going up. By the time you going down, you already get used to the steep slop.

Thank you again for the Camp Site.

BTW: the lake in your photo is really yosemite lake? If it is by 120 on the way to Tioga Pass, it is Tenaya Lake(?).
