Does anyone have any suggestions for cold weather observation techniques? There have been some really clear but cold nights here lately. While one side of me wants to do some observing the other side of me doesn't want to end up a meatsickle. I have observed comfortably down to -20C for many hours unsheltered on the open lawn. Though I don't tend to observe when it is windy. But only because it makes my eyes water too much to see anything. I start with two loose thin wool jumpers over a t-shirt.I wear a roomy down jacket over a comfortable (not tight) down waistcoat. I have several choices of down jacket and waistcoat as I seem to collect them. Roomy golfer's(?) thin wadding insulated trousers go on over loose fitting fleece trousers or skier's high-waist wadding insulated trousers. Down trousers are available but they flatten where you sit down. So I prefer sitting on wadding which doesn't flatten. A roomy, woolly tea-cosy hat is worn over an open face, non-allergenic balaclava. Gloves I don't usually bother with. I just tuck my hands into the jacket pockets once I'm on a target. But damp fingers can stick to cold metal and I have a pair of comfortably large Thinsulate insulated suede gloves with fine knitted sides to all edges for flexibility. I tried tighter fitting gloves for more dexterity and quickly got cold hands. I wear one thick pair of wool socks over one thin pair of thin wool socks. I'm still experimenting with boots. Rooomy rubber wellington boots are handy when there is snow or heavy frost on the ground but not really suitable for long periods of wear as the socks get damp and wick heat away. Usually I am more than comfortably warm in all this kit and rarely bother to even close the jacket unlss there is a breeeze. Thickness of insulation is everything as is multiple layering to trap warm air and reduce air (and heat) exchange. Always wear loose clothing, never tight. As it simply flattens the insulation. Removing hats is the best way to loose exceess heat fast without chilling yourself if you have to get a bit of exercise moving something heavy. Body moisture must be allowed to escape. So never wear anything waterprooof when it's cold. Or you'll sweat, then freeze, just as your insulating clothing becomes anything but insulating. The wetness collapses all that expensively trapped duck or goosedown into a thin soggy mat. I have heard that some animal skins are even warmer than goose down when temperatures get very low. -40C? Ask an eskimo. Chris.B |

A second wool hat over the first solved my cold toe problem. Ah, this is good to know: two hats on one's feet to solve the cold toe problem. So, where do the shoes go, over the insulation for the head? :-) Hand warmers in the pockets. A shelter from the wind, if possible. Make sure you are not dehydrated. A lot of people don't know how to determine if their body is telling them it's dehydrated. A l-o-n-g time ago a doctor told me to note the color of one's pee -- if it's yellow you're dehydrated. Conversely, don't drink too much water as it can upset the body's sodium balance and cause cell expansion and rupture. The local news recently reported a bicyclist in a marathon drank way too much water and died because the brain couldn't expand any further in that person's skull. Eerie. Equipment can be a problem too. My wife was out last night and her eyepieces kept fogging over because her eyes were watering and very mosit. A Kendrick eyepiece heater, or heated eyepiece box would be good. For the eyepiece(s), not the eyes! :-) |
