Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or support the project for an enhanced experience here.

Can anyone identify this fish

MY friend caught this in a high mountain lake in wyoming. Never seen anything like this, wondering if anyone knows what it is.

Sameguy-

My guess would be Oncorhynchus clarki utah, which has a common name of Bonneville Cutthroat Trout.

I think it is Oncorhynchus clarki lewisi, the westslope cutthroat. Bonni's tend to have more of a yellow hue. There are resident westslopes in north western WY, and as you said you were fishing a high mountain lake, my guess is you were in this region.
