unknown fritillary

Due to location I am starting to lean toward Arctic Fritillary, Boloria chariclea. It was small enough that my first guess(before it stopped) was a checkerspot. We were at or above 6500 feet. Unfortunately, the last two pics are the only ones with even a hint of the underside. The last one shows him on a catspaw, a dandelion like flower that is if anything, smaller than a dandelion. The wingspan is thus, under 2 inches
