Shelter placement and wind direction.

It's almost one of those instinctive things, build your shelter with its back to the prevailing winds, it offers you protection right? Yes but it can also cause problems



Looks good on an elevated rise to avoid a cold sink, back to the wind and room in front but..
The wind races over the slanted roof causing an acceleration of air draft resulting in a drawing effect towards the shelter..



And once you light your fire the draw will suck any smoke directly into your shelter.
I made this a very smokey fire intentionally to show just how the draw works in a strong wind and you can clearly see how the smoke bends into the shelter just like an eddy in a creek or stream.
When building a shelter with strong prevailing winds build it so that the wind is parallel to your shelter and draws the fire to the side, it could save you a lot of heartache if you've spent a long time building.
