On May 8, ANC 5A circulated the announcement from National Park Service below

The National Park Service has announced today that it will install “No Trespassing” signs around an area of Fort Totten Park where two canisters were found a few weeks ago. Fencing and barriers will be installed around the area where the munitions were found until further testing can be completed. Unofficial trails through the woods are also closed off.  

The park is closed east of Fort Totten Drive, south of Gallatin Street/Metropolitan Branch Trail and north of Brookland Ave NE/Farragut St. A majority of Fort Totten Park is open for recreation, but visitors should stay on the Metropolitan Branch Trail and the grassy areas of the fort itself (near Fort Totten Dr. and Crittenden St. NE).  

We are still awaiting the results of testing of the two objects found.
