Photo by @chamiltonjames / Charlie Hamilton James - a large male mountain lions stalks along a track below a cliff a few nights ago near Grand Teton National Park, Wyoming. Mountain lions often walk below cliffs to conceal themselves from prey animals. This cat triggered a camera trap that was set up specifically to photograph mountain lions. Despite the click of the camera and the flash guns firing mountain lions don't seem to mind camera traps and will sometimes hang around looking at the camera. shot on assignment for @natgeo society
