Just before it flows past Washington, DC, the Potomac River builds up speed and force as it falls over a series of steep, jagged rocks and rushes through a narrow gorge. Great Falls Park offers tremendous views of this powerful, natural spectacle. Hikers enjoy several trails along the river and sometimes gasp at expert kayakers who brave the falls. This sunrise picture was taken on the Virginia side of the river. Photo by Yin Lau. Posted on Tumblr by the US Department of the Interior, 9/14/15.
Mount St. Elias looms over Wrangell-St. Elias National Park & Preserve, our nation’s biggest national park. With towering mountains, county sized glaciers, diverse wildlife and scenery like this, it’s no surprise that this Alaska park is also a World Heritage site. It doesn’t reveal its wonders easily, but for the adventurous spirit, the rewards are limitless. This image is from a recent flyover of the park by the National Park Service.
