Have you ever been in a forest or large swamp. I have and if you are not inimatly familiar with the area you will get lost. The PCs in my games get lost if they are not using their intuit direction skill. Try making a large overland journey without any type of direction finding device through a heavily wooded area. You can get a general sence from where the sun rises/sets but when if you can't see the sun for a number of hours?
I have, too. If the sky is really, really overcast, it might be an issue. Otherwise, assuming you know the rough time of day and the season and the hemisphere (things that you'll generally know), you perform the following steps:
1) Look for a patch of sunlight at least 3 inches across. You can almost always find this, no matter how thick the forest -- I've performed this experiment in the old-growth temperate rainforests of the Pacific Northwest.
2) Stick your finger in the patch of sunlight, pointing at the ground.
3) Look at your finger's shadow.
4) Assuming you're in the Northern hemisphere and that it's not midsummer and that it's midafternoon, the sun is gonna be in the southwest part of the sky. That means your shadow will point northeast. If it's morning, your shadow will point northwest. If it's noon, it'll point north.
It's pretty simple -- more simple than, for example, tumbling through an ogre's reach in the middle of combat.
At least, in my experience it's easier
