Zombie fire
Similar to a forest fire, a zombie fire is when a large horde of zombies catch fire. A zombie fire happens when a zombie horde is so close-knit that when one zombie catches on fire, the fire rapidly spreads to all the other zombies in the horde; just like kindling. The use of molotov cocktails on zombie hordes is a known cause of the zombie fire phenomenon.
"Hey, Phil, what took you so long?"
"We ran into a zombie fire on the way here. Someone must have thrown a molotov cocktail into the horde or something."

Zombie fire
It seems like a smoldering wildfire would melt all the snow packed on top of it. Even if people are told the fires that start in the spring in Siberia come from wildfire smoldering under the snow, it seems like the snow would either extinguish the fire or melt in the process.
Zombie fires a little bit hard to believe.
