PHOTO OF LASTING INTEREST

Gone Fishin’

Although human visitors to Katmai National Park in Alaska are required to complete a “bear etiquette” orientation, the bears make no offer of their own hospitality. As the salmon in this 2017 photograph are about to find out, brown bears rule at Katmai. Around 2,200 of them roam the four-million-acre park, compared with the 60 campers allowed at the park’s only established campground. Photograph by Art Wolfe
