How far can you see in thick fog when walking?

In thick fog, visibility can drop to anywhere from ten to fifty feet, depending on how dense it is. This means landmarks and even nearby features can completely disappear, leaving you with only what's immediately around you.

Why is it so hard to judge distance when walking in fog?

Your brain relies on visual references to estimate distance, and fog removes all those references. Without being able to see landmarks or changes in the landscape, you can't tell if you've walked two hundred metres or half a kilometre, making it easy to overshoot or undershoot navigation points.

What's the best way to navigate when you can't see landmarks in fog?

You need to use proper compass bearings, count your paces to measure distance, and time each leg of your route. It's old-school navigation that requires actual concentration, but it works reliably when visual navigation isn't possible.
