I walked across a vast field towards a bull elk and his harem of ten females. As I drew closer, they spotted me and fled toward the steaming geysers in the distance. There is a sense of grandeur in the sweep of this image. The male elk is on the far right – he directs the flight of his harem by veering towards it. The columns of rising steam tell us we are in Yellowstone and offer a dramatic context. We have two natural processes – the elk mating season and the eruptive geysers – going on simultaneously in this image.
