The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This is an interesting one. Following the keys in Merritt R.W., Cummins, K.W., and Berg, M.B. (2019) and Jacobus et al. (2014), it keys clearly to Ephemerella. Jacobus et al provide a key to species, but some of the characteristics are tricky to interpret without illustrations. If I didn't make any mistakes, this one keys to Ephemerella mucronata, which has not previously been reported any closer to here than Montana and Alberta. The main character seems to fit well: "Abdominal terga with prominent, paired, subparallel, spiculate ridges." Several illustrations or descriptions of this holarctic species from the US and Europe seem to match, including the body length, tarsal claws and denticles, labial palp, and gill shapes. These sources include including Richard Allen's original description of this species in North America under the now-defunct name E. moffatae in Allen RK (1977) and the figures in this description of the species in Italy.
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.

Coppler Creek Canyon at the powerline cut, easiest access to a tight little brookie stream in a steep gorge
Joe and Todd heading down into the creek
Into the creek they go...
A cool canopy of northern white-cedar and cold, clear brookie waters
"You see any, Joe?"
"Yeah, I do now!"
Looks like a good huff-n-puff climbing out...I know, did it a few times already!
The boys provided just about all of the food this trip, as usual
I did have to do some dishes...
Joe brought some delicious cheeses, I think his facial expression is a reflection of that
Todd was so impressed by my "classic wets and streamers" box (yes, I tied all of them) he snapped a pic with Joe & I in the background
Todd's canoe, briefly deployed before the wind blew us off the Millpond
Nest with 5 (at least) baby eastern phoebes right above my front door...that fledged the day after the boys left!
Hognose snake the boys saw on the trail into the Canyon
Milkweed with monarch caterpillar! on the hike into the Canyon
The Beer Display, lovingly created by Todd
Close-up on beers...
No idea where they find these...
Mike will approve of this one!

Here's the pics of the boys hiking into the Coppler Creek Canyon & other miscellaneous fun. Enjoy!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Beautiful pics, those streams are beautiful. Look like something I would enjoy throwing my 1wt around in. Those beers all local brews?

I have a 6 1/2-foot 2-weight setup I got just for these cute little creeks! You just CAN'T use anything bigger, unless you want to spend all of your time unhooking your fly from everything but fish...

NO IDEA where the guys find their "strange brews", they must both know some really fancy beer stores! I don't drink anything alcoholic these days so I am clueless on exotic beers and liquors and etc. Iced tea or root beer are my preferred thirst relievers.
