This dun is almost certainly of the same species as this nymph, as it hatched in my cooler from a nearly identical nymph.
This mayfly was collected from Nome Creek on July 10th, 2011 and added to Troutnut.com on July 13th, 2011.

Looks like a female Cinygmula ramaleyi sub to me (one of many Little Western Red Quills). The other common Western species are larger and/or have different colored/patterned wings. While only three are common (if that word can be used), there are nine species currently listed with a NW distribution, but I don't know about AK. I guess it remains possible to be one of the less common species that may have virtually identical morphology and color.
