Blue-winged Olives
Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

Dorsal view of a Setvena wahkeena (Perlodidae) (Wahkeena Springfly) Stonefly Nymph from Mystery Creek #199 in Washington

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.

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.

Swampbuggy Lake. This is one of the prettiest scenes where the road winds along the Clearwater Mountains.

Clearwater Mountains. This general area was the site of much of my frantic hunting action on the last day of the season, at morning and dusk.

Glad you didn't give away all the good fishing holes on the Denali Highway. Lived up there for 23 years and that road has some of the best Grayling fishing I've ever seen. I know there are a dozen little streams names Fish Creek in AK, but am wondering if the Fish Creek in your pictures in the same as the one on the Denali Highway. Nice Job

The Fish Creek in my pictures isn't the one on the Denali Highway. It's true there's good grayling fishing all up and down that highway, but the same can be said for most of interior Alaska if you do some leg work off the road and explore.
