I recently went on a snow camping trip where the temperature dropped down to around 0 F. I decided to use my standard Pocket Rocket style stove with an upright canister that screwed to the bottom. I decided it to get it to light by keeping the canister warm.
On the trip, my friend had a Kovea Spider which can be used as a remote inverted stove. He used a canister he did not pre-heat. He opened the valve on it. It’s not entirely clear what happened, but we think that the gas was released, hit the cold stove, and liquefied. When he lit the stove, it burst into a huge flame. He pulled it away, and the snow actually caught on fire and burned for a bit.
I incessantly mocked him for lighting the snow on fire, but then I did something even worse. It was stupid. I tried to keep the canister warm. I hooked up my upright canister stove. I opened the valve and the gas started coming out. I had a bit of trouble getting it to light, so the gas ran for a bit longer than I hoped. Eventually it lit, and apparently I had the same problem. The gas liquefied onto my stove. Since it wasn’t a remote stove, it didn’t liquefy on the snow as well, it liquefied on the canister.
Not only did the stove catch fire, the canister caught fire! My initial attempts to stomp it out failed, so I quickly threw it into the powder nearby. That put it out. Fortunately, the canister was fairly cold, or else I could be dead right now.
Now I was left with a stove covered in ice that couldn’t light even if I wanted to. I didn’t want to. I borrowed water from a friend.
Despite the weight penalty, I’m buying an inverted canister stove. If I set the snow on fire, I’ll turn down the gas and spend the minute or so to let it burn off.
