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

I was not fishing, but happened to be at an unrelated social event on a hill above this tiny creek (which I never even saw) when this stonefly flew by me. I assume it came from there. Some key characteristics are tricky to follow, but process of elimination ultimately led me to Sweltsa borealis. It is reassuringly similar to this specimen posted by Bob Newell years ago. It is also so strikingly similar to this nymph from the same river system that I'm comfortable identifying that nymph from this adult. I was especially pleased with the closeup photo of four mites parasitizing this one.

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've just added a new panoramic picture to the landscapes section. Have a look. :)

It's one of those places I could be shot for naming, even though it's not a huge secret. Those of you familiar with the Catskills might recognize it, but please don't say where it is.

I just got a new high-end Mac (my first non-Windows computer, I love it) and Photoshop CS3, which has a feature to stitch panoramas together. So I took ten pictures while pivoting my camera around in a circle on the tripod, and this is what I got when I put them together. I think it's a neat feature and I'll be playing around with it more soon.
