Didn't end up getting much fishing squeezed into our yellowstone trip(a couple browns on Nez Perce, my son got a YCT on a rooster tail from the lake), but did catch this video from the yellowstone river:
Yes. There was a small pocket water there where we could see them stacked up. I was able to see maybe a dozen jumps and caught 2 videos, posted the better of the two.
watched for maybe a half hour.
Fishing is the most wonderful thing I do in my life, barring some equally delightful unmentionables. http://www.adiposefin.com
