Two moose wading in lake with snow-capped mountains, Denali National Park, Alaska

Weighty waders

Though they're mainly crepuscular creatures, moose can sometimes be spotted in the daytime. Especially here in Alaska, which has the biggest population of moose of any state, estimated at up to 200,000. Even in broad daylight, though, bull moose have few predators to fear given their sheer size, sometimes more than 1,500 pounds and with antler spans over 6 feet. These two comrades can't throw caution completely to the north wind, though—they share the lands around Denali (pictured in the background) with a healthy cohort of brown bears.
