National parks and protected areas are brimming over with water scenes, from glaciers to snowy landscapes to ponds to rivers to misty mornings. Contributing photographer Rebecca Latson provides tips and techniques for how to capture those myriad forms of water (glaciers, snow, ponds, streams, rivers, mist, clouds) in a composition.

A "spectacle of nature," in which the Muldrow Glacier in Denali National Park and Preserve has suddenly surged forward for the first time in more than six decades, has created a scientific window for glaciologists to better understand the park's rivers of ice. Though highly unusual, the glacier's rapid movement is not believed to be linked to climate change but rather due to the "unique nature of the structure and composition of the glacier’s ice, its surrounding rocks, and the topography it is moving through."

Portions of the Denali Park Road in Denali National Park and Preserve will be open to private vehicles this summer, though you'll need to make a reservation if you want to cruise down that road.
