The Wyoming and Montana Rockies are hands-down my favorite mountains, but nowhere has rock quite like the Sierra. It truly does seem to have a shine to it, and Muir was spot-on when calling it the "Range of Light."
The shine on Sierra rocks may be due to the fact that they are granite. This particular section, Ministry Wall, has a different sheen than the surrounding rocks. It does have a black glaze with holds that are sharp and angular.
Well, Pratt's Crack has been there for millions of years, and I guarantee that it will still be there when you come back for it.
I have a question, how did you recognize it from the other photo that was showing only the upper part of it?
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
