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.
This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.
On the last day of this year's Montana trip, I had a fun visit in the morning with Pat Clayton from Fish Eye Guy Photography, who I think it's safe to call the best trout photographer in the world. He recently opened a brick-and-mortar gallery in Philipsburg showcasing some of the best of his must-see work. I didn't take any pictures there (taking pictures of pictures would seem odd), but check out his website if you haven't seen it.
I did snap a quick photo of the Columbia River from a particularly scenic spot on the long drive home to the Seattle area.
