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

I like this one. Glacial river, taiga, tundra, and the perpetual ice cover of a massive high ridge dozens of miles away in the Wrangell 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.

I am looking for reliable keys, preferably published books or articles, that can be used to identify aquatic inverts to species level. I am currently using such sources as Pennak, Wiggins and Merritt & Cummins for both work and play. These sources are great at getting to genus level identification.

Does anyone have any suggestions?
