雪地露营体会

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：

引用:
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
