National Park Service
Rock Creek
The National Park Service installed this picture post in 2015 to encourage visitors to Rock Creek Park to become citizen scientists by documenting the conditions they experience that day. Scientists use photographs as records of a scene. We need your help to document the plants, clouds, and seasons—and how they are changing in response to a warming climate. Use the picture post to take photos and upload them here.
