Rock Creek Park and Teahouse Dam by StreetsofWashington Via Flickr: An early 1900s view of Rock Creek Park, showing the Teahouse Dam and Beach Drive. This view is facing north on Beach Drive, just past the intersection with Tilden Street/Park Road. Beach Drive is still a dirt road, and there's no parking lot yet. Peirce Mill is just out of view on the left side, across the creek.
