Which structure is least likely to be threatened by fire due to wind patterns?

Structures surrounded by wetlands are least likely to be threatened by fire due to wind patterns because wetlands typically create a more humid environment that can inhibit the spread of fire. Waterlogged soils and vegetation in these areas absorb moisture, making them less flammable. Additionally, wetlands can act as natural fire breaks by providing barriers of wet conditions that are less conducive to fire behavior.

In contrast, structures in canyons may experience the funneling effect of wind, where gusts can become stronger and more unpredictable, increasing the risk of fire spread. Structures on ridges can be highly exposed to winds, which can carry embers and flames, making them more susceptible to fire. Leeward positions, while somewhat protected from wind, can still face threats from embers that are carried by the wind from a fire, potentially igniting fires in otherwise sheltered areas.
