Elk hair caddis of course.
From the inbox:
Greetings from Big Sky,
The other day when fishing the Firehole River inside Yellowstone Park, I was able to get some great shots that I thought you guys might be interested in throwing up on the blog. I had left my rod laying on the bank as I strolled downstream to take a break. As I was walking back up, I noticed this cow elk milling around right where I had left my rod. Next thing I know, she is picking it up as if she wanted to give it a try. Once I was able to reclaim my rod I was able to put some browns on shore that were looking up at salmonflies and golden stones. Photos courtesy of myself.
Enjoy,
Josh Berry
