The scene could have been in a period film -- a handful of men wrapping rope around a mule to secure metal tanks to the saddle.
The mule was neighing. Water nearby was rushing. There was no motorized traffic for miles.
The mule then marched up a steep canyon, transporting the precious cargo.
Inside the 10-gallon metal tanks were water, ice and Yellowstone cutthroat trout.
