雪地露营体会

lulululu

这次只有我和小归在湖边雪地扎帐蓬，只有小归坚持下来了，我半夜狼狈出逃，离开时的温度是-25C 度，除了极少数极端情况，－25到-30度这已算我们在local mountain能体验到最低的气温了。

考虑到在现有装备下能改进的地方很多，我还会再试，吸取的教训如下：

1。扎帐逢的时间要早，最好是在天黑之前，第二天看到西人到达后的第一件事就是在阳光充足的下午扎营，再做其它事情，我和小归是晚上十点钟出去扎帐蓬的，这时气温已降至很低，身体热量流失很多。

2。一定要吃饱喝足身体才能暖和。另外天冷的话，酒也要少喝。喝多了会冷。这也是为什么醉酒的人更易冻死。

3。热水袋非常有用，穿的盖的再多，也只是绝缘，首先自己的身体要暖和。or use 1-litre bottle of hot water, with tea bag inside, wrapped in a fleece hat or sweater.

4。睡觉之前一定要先上厕所，here's why

- our body is working overtime, trying to keep useless water at body temperature. we must get rid of that water asap, otherwise our body - with its limited, tired, resources - will only be able to keep us warm to a limited extent.

5。封闭好的烛灯笼(fully-enclosed little candle lantern)即安全也能提供一些热源。

6。还是两层睡垫，底下一层用泡沫或塑胶的，上面用充气睡垫。如果怕冷，可以选厚些的睡垫，all weather emergency blanket可以用来垫一层盖一层。因为现在多是一个晚上的camping,所以就是闷气也影响不大。

7。头和四肢散热最多，帽子厚袜必备，如果是穿着bootie睡觉会更暖和

8。睡袋边放些巧克力或能量棒，随时补充热量。

9。羽绒服防寒非常有效，特别是雪地露营的话，穿着它睡觉比N层的衣服或轻薄的PrimaLoft绵衣有用的多。小归穿着羽绒服，我穿的是Primaloft jacket, 防寒效果差很多。雪地高寒露营，显然羽绒服是无法替代的。

10。冷空气下沉，尽量不要选在低气压的地方扎营，比如高山湖边，就是选湖畔高出几米的地方，情况也会好很多。

11。share帐蓬，这次我们六人背了六顶帐篷。很多是二人帐篷。有些浪费。share帐蓬能使帐蓬内温度提高不少,这是CT上的一个相关回复,我觉得很有道理：

everyone just thought it was normal to share tents, and groups like the VOC and BCMC even had stocks of 4-person tents for trip use by members. Choosing tentmates was just part of organizing trips, and as you can imagine was an important part of the fun and games. Eventually many or most of the bivy sackers realized tents were better unless you were stuck on a cliff somewhere, and switched. But they switched to single tents. What a waste of body heat and socializing. I mean, we go on group trips to socialize, don't we?

12。鞋子可用塑料袋包好放入睡袋底部以避免鞋子冻僵不能穿着


先写这么多。

假如是零下25度的话，住帐篷本身就有点不智

零下25度睡帐篷完全可行，而且并不少见。请参看相关讨论，在我改进我此行得到的教训后，我还是会再次尝试的 :lol: 。

上次在BREW HUT和我们一起吃火锅玩杀人游戏的Bob的建议：

Gloria, I think you need to add more carbohydrates to your winter diet. Carbs will fuel your body warmth fairly quickly and then run out sometime between 1 and 4 AM. If you're lucky the protein in your dinner will then kick in to keep you warm. Yes, do keep chocolate or, even better, a carb based energy bar in your sleeping bag. It acts fairly quickly and will let you get a bit more sleep. Just remember to put it into a pocket or something in your bag or else it will be frozen solid when you want it.

Also getting dehydrated makes you more susceptible to the cold. Make sure you drink lots of warm liquids.

My experience with overbags is similar to Jeff's. The overbag (MEC Emp Penguin - grey) trapped moisture in my sleeping system. I'd wake up feeling damp. Fortunately, while the nights (5) were in the -20 range the days were crystal clear and the sun dried everything in the tent daily.

Also on the topic of sleeping bags and to expand on something Dru said. If you are in temperatures way colder than your down bag is rated for any inconsistancy in the placement of the down will create cold spots. Make sure you fluff it up. Make sure the bag is cleaned regularly and the 'down puffing' stuff (forgot the name right now) is used - it realy works well. Watch out for older down bags - once the down gets 'tired' it doesn't work. Can't afford a new one? Buy a liner and rent one.

This past weekend the nights were all -25 and my tent was -15 in the morning. Another person with a MH Trango2 had the same internal tent temperature the first morning. For the last 2 nights 2 people slept in that tent and the morning internal temperature dropped to -8 for them while I was still at -15. A second body in the tent makes a big difference.

I also find that when Ladybug and I zip our bags together it adds about 5 degrees to the range of the bags. Mind you these bags are the same except one is right zip (ladies short) and one is left zip (men's med.) so the internal baffles work properly when zipped together.

When the temperature drops to or below -10 and you are camping don't drink alcohol. You pay for it all night long.

Hot nalgene bottles? Brilliant! However those outrageously priced OR nalgene cozies that hang on the rack accross from the fifth cashier station at MEC are also worth every penny. I bot one last Wednesday for a 4-day backcountry ski camp with some trepidation (I though everyone would laught at my shiney new expensive brand name nalgene cozy!) only to find everyone else had one too (of various vintages mind you)! They keep you drinking water from freezing all day long. Filled with boiling water and tucked between your legs while sitting around chatting before going to bed keeps the major arteries in your legs, and therefore your feet, warm. Reheat the water before going to bed they will help keep you warm all night. If you are all bundled up inside your sleeping bag it takes forever to heat up the insulating air in your thermarest. The hot nalgene takes care of this pretty quickly.

Another fan of booties here. However, regardless of which one you buy, get an insole for them. The fibre kind we used to put in rubber boots works well. 3 Vets has some with heat reflective foil on one side. They make the booties much warmer. While I would have preferred synthetic I bot some of the MEC expedition booties and put an insole in them. My feet were always warm (except when I put my frozen ski boots on each morning ). You don't need the bootie insulation to go much above your ankle but the cover or gaiter part should go to your knee. Helps keep snow out. I meant to check out Taiga for booties but forgot so I'm not sure what they have. No room for an insole? Take a small piece of blue or yellow foam to place on the snow under your feet.

Anyways, after all that, winter camping is a lot of fun and No Bugs! Hope these comments help.
