There is usually one snow patch on the trail just left of the picture above where snow remains for some weeks. A groove often wears into it from so many hikers, that can be several feet deep.

The last water on the trail is always at switchback #22 above Trail Camp. It runs across several switchbacks. The source is a snow field high above and off-trail, and it dries up late in summer. This time of year, it might be frozen early mornings.

And many people will just dip and drink that water. It's about as pure as you can get.
