Yes, I have concluded that facing uphill is the correct answer to my question. I confirmed that yesterday when I went back to a similar spot and landed it on a slight uphill slope.
BTW, here is the object I was trying to photograph. It is a mysterious light that someone erected two years ago in the middle of a huge (thousands of acres) wilderness area overlooking Carmel Valley. It is in the middle of 10-foot high brush, on a steep slope, which makes if very difficult to get close without crashing the drone (thank you DJI for the collision avoidance alarms).
I can't find any path leading to the light. It appears to have been attached to a sapling tree trunk. So, thanks to my
Mavic 2 I now know what it is, but am no closer to understanding why someone put it up nor do I know what its purpose may be.
