Blue-winged Olives
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.

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.

Hike in the Clearwater Mountains in the Alaska Range (Day 2 of 4)

By Troutnut on July 6th, 2013

We got a late start to day two because we were tired and it was raining all morning and early afternoon. We began around 3:45 pm and made our way up over one pass and down the next drainage to the ridge before the next pass. We were able to break camp during a brief pause in the rain, but we went through the pass amidst howling winds and small hail. Later in the evening, the weather cleared enough for a bit of sunshine.

The only wildlife we saw were Arctic ground squirrels and a cow caribou with two calves.
