The weekend before Memorial Day of 2023, I took a trip to Washington DC. After checking in to my AirBNB on the 24th, I found I had a decent amount of time in the day available, so I took the bus north to Rock Creek Cemetery to graves of Stone, Field, Van Devanter, and Harlan I.
Van Devanter's stone has the name "VAN DEVANTER" prominently displayed of the stone itself and is thus fairly easy to locate.
Also buried in this cemetery are Gore Vidal, Tim Russert, and Upton Sinclair.
