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.

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 saw something interesting tonight at the end of a completely unsuccessful trout fishing trip. It was dark and rainy and, for added darkness, I was under a bridge. I was looking around the shallows with my flashlight when I saw a very small rodent come running to shore from the middle of the river and disappear into the rocks.

It was so FAST that it had to be running across the surface rather than swimming. I didn't know they could do that!
