I co-shot this piece last fall for National Geographic (with fellow filmmaker, Stephani Gordon, and NGTV producer and friend, Laura Boyd).  The featured Explorer, Joe Riis, does amazing work and his stills (used throughout the cut) are incredible.

Pronghorn are extremely timid and they have extraordinary vision – they can detect the flick of a finger from hundreds of yards away.  So I spent quite a bit of time waist-deep in snow, pushing my telephoto to the maximum, and minimizing my movement as I operated the camera.  It was a tough task… but persistence eventually paid off.
