What we know
We have little on American Federation of Human Rights headquarters so far beyond its location. If you know its history, please add it below.
Where it was
Read from the 1956 Douglas County map inset of Larkspur with handwritten labels (Larkspur Book 1, Larkspur Historical Society binder 1 p. 220), georeferenced from its Secs. 27/28/33/34 corner (T9S R67W) and its 0.3-mile scale bar; good to about 200 feet. The same method puts the map's 'School' within 300 feet of GNIS's Larkspur post office, the old school building. Marr: 'The Federation of Human Rights built their headquarters in these pines west of town, and their members lived in the surrounding cabins' (Larkspur Historical Society binder 1); the 1956 map labels it 'American Federation' west of the Santa Fe tracks.
Placed from a written description, such as a land section, a distance from a landmark or an old survey note.
