One reason the National Park Service has such a hard time reducing its maintenance backlog is the fact that very little stands still in a national park environment. At Yosemite National Park in California, for instance, slippage that damaged a section of the Big Oak Flat Road has kept crews working, and maintenance costs escalating, since late February.

Plowing operations are under way at Glacier National Park, where crews are working to clear the Going-to-the-Sun Road of the winter's snowfall. Once that work is done, construction on parts of the iconic parkway could create some delays for travelers this summer.

Still imagery is wonderful for capturing a moment in time and freezing it in pixels suitable for framing, but what do you do when you crave the sounds and movements as well as sights of a favored national park? Video is a great platform to do just that and photographer Rebecca Latson demonstrates different options for capturing a national park's sights, sounds and movements.

A "sampler" begun by young Martha “Patsy” Fitzhugh before her death in 1793 has returned, Chatham, the place of its creation. It’s likely the sampler has not been at Chatham since the Fitzhugh family moved away from the house in 1798. The sampler will be on display at Chatham at Fredericksburg and Spotsylvania National Military Park for the next three months.
