Threading through the backcountry, and frontcountry, of Yellowstone National Park are creeks and streams fueled by springs and snowmelt, some only several feet across, some dozens of feet wide. More than 300 topple over waterfalls at least 15 feet high, while others meander placidly through the Lamar and Hayden valleys.

Great photo spots in the national parks often tend to lead to wide, crowded spots in the road if there's not an overlook already established or the one that exists is too small. At Denali National Park in Alaska, officials are working to "uncrowd" one such spot and make it safer for you to pull over, enjoy the view, and snap a few photos.

Is that a black bear cub? A badger? No, it’s a wolverine! Wolverines have distinct color patterns on their face, neck and chest making each individual animal unique, and are referred to as “skunk bears” by the Blackfeet Indians. Though their appearance leads most to believe them to be a relative of bears, they are the largest members of the weasel (mustelidae) family that exclusively live on land.

A storm event that sent floodwaters and rockfalls across the Denali Park Road also has led to the evacuation of 103 guests and employees from a lodge in Denali National Park in Alaska.
