Standard practice for decades in the Grand Canyon.

And when I was in the Sierra Nevadas over a decade ago a requirement for hiking the trails (John Muir Trail for instance). Had a long conversation with a hiker I met at Devils Postpile who I gave a ride to from Mammoth Ski Area down into the town and he had his bucket with him and mentioned that it was a requirement.
