The Confounding Mystery of the Red-Brick Manor at Harmony Hall

Broad Creek straddled two worlds in the 1600s: that of the Piscataway people, for whom the land likely constituted important hunting and fishing grounds, and that of the European colonists who settled it starting in 1634. While the Broad Creek community prospered as an Atlantic port city before collapsing due to the American Revolutionary War, one estate—and Harmony Hall, the stately red-brick Georgian manor house that renamed it—weathered it all.

Updated Species Database Will Help Boost Amphibian Conservation Across the National Park Service

To steward amphibians effectively, managers need basic information about which species live in parks. But species lists need constant maintenance to remain accurate. Due to recent efforts, the National Park Service now has an up-to-date amphibian species checklist for almost 300 parks. This information can serve as the basis for innumerable conservation efforts across the nation.
