Fritillary on Lone Mountain - Speyeria

Fritillary on Lone Mountain - Speyeria
Big Sky, Montana, USA
September 4, 2019
I photographed this butterfly on a walk on Lone Mountain at Big Sky, MT, between the upper termini of the Swifty Lift Line and the Shedhorn lift -- the south-facing slope of the mountain. A fellow member of the tour found the altitude to be about 9400 feet (via a hiking app). I'm guessing it's a Callippe fritillary (subspecies gallatini??) based on your images and location data.

Moved to Speyeria for expert attention.
