Look at this great photo from 1890. It shows a group of people riding their horse and buggies through Rock Creek Park. I don’t suppose any of you recognize where this is? I know, that’s a long shot.

Based on the map at https://ghostsofdc.org/2013/07/13/motor-roads-through-rock-creek-in-1922/ , there were three fords as of 1922, a few years after this picture. One was just south of Klingle Road, one was for crossing Broad Branch, just north of Broad Branch Road, and one was Milkhouse Ford, which still exists, just north of the Miller Cabin.
I am quite sure that this picture is of the ford just north of Military Road and that it is located in the V-shaped area of the snapshot below. The road was straightened out later, in the late ’50s I believe, as a bridge was built to obviate using the ford.
Millkhouse Ford – part of Milkhouse Fort Road. Its north of Military Road on Beach Drive.
Here it is today
