Summer up north belongs to the bears. When the sun reigns, so do the brown bears of Alaska—like this mother and cub in Katmai National Park and Preserve, about 260 miles southwest of Anchorage. Also known as grizzly bears in Alaska, the brown bears pack a year of living into the summer months, foraging, feasting, frolicking, fighting, and mating under skies of nearly perpetual daylight.
