Grayling & bugs on the upper Gulkana River

By Troutnut on July 17th, 2011
We went sightseeing in the Alaska Range on Sunday and made a quick stop near where the Gulkana River crosses the Denali Highway. Wader issues prevented us from venturing very far, so we were confined to a long stretch of easily accessed pocket water containing about two pockets, which held one nice grayling for each of us. Once again, Lena caught the first fish, giving my neuroscientist wife her chance to debut as a fashion model for the Troutnut store:



(Any wives reading this can buy "I outfish my husband" stuff here.)

I also collected some nymphs and a beautiful Drunella doddsii dun to photograph.

Hi Luke -

If info comes along later refuting the placement, we'll just have to move them... But this is the angler in me speaking.:)


:)Indeed


Just to clarify, you do understand I meant for angler oriented sites right? Don't want you to think I'm a total luddite.:)

I enjoyed the post. My father grew up in that part of Alaska and the Gulkana was one of his favorite rivers. He talks about that river all the time to this day, so I found this pretty interesting. Great pictures, thanks a lot!

Luke -
if someone figures out the nymph associations for western Cinygmula, and can id the species, let me know...


Excellent point that can be applied to genera in a lot of families. The best we can do with photos of the "tough ones" is apply descriptions from science/reputable angling texts as best we can and go with what seems most reasonable. The most often used words should be "probably" and "possibly". If info comes along later refuting the placement, we'll just have to move them. I think this a better way to go then simply throwing everything into familial or generic categories unless determinations can be made with absolute certainty (which is impossible with most photos in the first place). But this is the angler in me speaking.:)

Regards,

Kurt
