Some years ago, I used Polaris as an approximation. Then, I went through a period of using a yachting compass (hand-held) and figuring in variation (magnetic vs. true North), I have now gone to using GPS. If I stand under the tower and take a reading, I can march either North or South along the same reading and put in a stake as far as I can see the tower. I then jiggle the antenna to point toward me if I am North of the tower, or away from me if I am South (I have the South stake set here a few hundred feet from the tower so it’s quite easy to tell). I also put in a marker for 270o  by marching straight West from the tower and putting in a stake.

From time to time (but not for the most recent two days), I do get some feedback about deploying markers in our garden.

I use Google Earth and find my home and a nearby reference point, like a building or powermast.
With the Ruler tool I draw a line between the two points and read the angle in degrees.
Next I turn the rotator to the obtained angle. Next I make the necessary adjustment so that my beam is pointing towards the reference point.

Powerlines are a nuisance most of the time, but occasionally they can be useful.

Use a tree, pole, tower or anything that casts a descent shadow. From
the Sun time table, when the sun is at 180 deg, the cast shadow points
to North 000 deg.

If you want E/W, run a string out along the shadow, put a tee-square
down, wala, E/W :-)

When I set up portable operation on EME DXpeditions, I just take along a printout of
the sun position from my GJTRACKER program for the day I am going to be setting up.

Usually, there is some time during that day when I can see the sun and verify the
azimuth calibration of my paper clip indicator:
