Brings back memories Marcel!  From the Boy Scouts a "few" decades ago (no, I'm not telling how many). Went along with night land navigation using visible stars. Also had this method in the US Army during SERE training. Thanks for putting this here. You can use this with watches that have rotating compass bezels. When sun is high in sky, you can use a pen/pencil or small twig vertically to cast a shadow to find 180 degrees from solar azimuth. An expedient plumb bob also works to cast a shadow.

Important Note:
Use local "solar" time, not civil time. My local longitude is 5 hours 43 minutes from Greenwich, not 4 hours EDT. Even if I correct for DST, it's still 3/4th hour off. Being able to correct for this accurately makes the direction more accurate.
