The National Park Foundation is investing nearly $2 million in park partners across the country, from the Friends of Mammoth Cave to help it establish a social media strategy to the North Country Trail Association so it can create a trail protection program.

Nearly four decades of Landsat imagery have allowed researchers to closely monitor the retreat, and advance, of some of Kenai Fjords National Park's glaciers. The study didn't pinpoint the exact cause of the glaciers' movements, but rather documented for the National Park Service the behavior of 19 glaciers in the park located about two hours southwest of Anchorage, Alaska.
