True North

I got the sunrise and sunset in local time, 24hr format, from sunrisesunset.com and calculated (sunrise+sunset)/2. That came out to 13:09. So at lunch I aligned my SteppIR boom shadow with the mast's shadow. It was off by about 37 degrees +/- 2 from what I had thought, which is shown here by the top border
line running what I thought was west-to-east. A look at Google maps showed me a 39 degree difference.
