Sightings are from a three-day backpacking trip to the Bighorn Mountains. Butterfly activity was suppressed on the first day as a huge storm moved in before noon, but partly cloudy conditions brought out flight activity when the sun poked through, and made for very cooperative butterfly posing when the clouds covered up the sun. Numbers were hard to track, so species that I only saw one of are indicated.
