茶卡盐湖一日 · 天空之镜

茶卡镇很小，就是为盐湖服务的镇子，住宿和饭馆都集中在大路边。早饭吃青海口味：羊肉汤、馍馍、油条、熬茶（用伏茶加青盐和花椒熬的咸茶，本地人喝这个）。镇子海拔约三千一百米，走路慢一点，别猛跑，有人第一天会有点头晕，是轻微高原反应。早上凉，比西宁还低几度，外套要穿。进景区前买好水，景区里贵。

Chaka town is small, existing to serve the lake, with lodging and restaurants along the main road. Breakfast is Qinghai style: mutton soup, steamed buns, fried dough sticks and aocha — a salty tea boiled with brick tea, salt and prickly ash that locals drink. The town sits at about 3,100 metres, so walk slowly and do not run; some people feel a little light-headed the first day, a mild touch of altitude. Mornings are cold, a few degrees lower than Xining — wear a jacket. Buy water before entering, as it is pricier inside.

进门后先是一片盐雕：西王母、成吉思汗、驼队、动物，都是用湖里出的大块青盐混着卤水一层层堆起来雕的。盐雕每年重新修，因为盐见水会化、见风会酥，能撑几年已经是本事。最大的几座有几层楼高，走近看，表面泛着淡淡的青灰色，是「青盐」的颜色。这里适合先把照片拍了，等下午光线平了再进湖心。广场风大，帽子拿稳。

Past the gate comes the field of salt sculptures: the Queen Mother of the West, Genghis Khan, camel caravans, animals — all built up layer by layer from large blocks of salt from the lake bonded with brine. They are reworked every year, for salt crumbles in wind and melts in water, and lasting a few years is already doing well. The tallest stand several storeys high; up close the surface has a faint blue-grey tint, the colour of 'green salt'. Shoot here first, then head for the lake centre when the afternoon light softens. The plaza is windy — hold on to your hat.

湖里铺着窄轨铁轨，是当年采盐运盐用的，现在跑观光小火车，从门口一直开到湖心码头，大约二十分钟。车是敞开式的，风从头吹到尾，坐着比站着稳。想走路的也可以沿栈道走，四公里多，晒。湖心的水面最平、盐层最白，「天空之镜」的片子基本都是在这里拍的。下车先别急着下水，找个没人的段落再下去。

Narrow-gauge rails run out into the lake, laid in the days of salt hauling; sightseeing trains now run from the gate to the lake-centre pier in about twenty minutes. The carriages are open-sided, the wind blowing through the whole way, and it rides steadier seated than standing. You can also walk the boardwalk — over four kilometres, and exposed to the sun. The water is flattest and the salt whitest at the centre; nearly every 'mirror of the sky' picture is taken here. Do not wade straight off the train — pick a quieter stretch first.

这是全湖最重要的一段：在规定的区域脱了鞋（或穿租的鞋套）走进水里，水深不过脚踝，脚底是硬实的盐层，有颗粒感，硌，走慢点。站在水里不动，等水纹平了，脚下就是一整面镜子——云在脚底、影子在身边，拍照的人排队也在所不惜。想拍出「倒影」要注意：离人群远一点、太阳角度低一点（上午十点前下午四点后最好）、穿颜色鲜艳的衣服出片。盐粒伤脚，有伤口别下水；中午紫外线极强，晒半小时就疼。

This is the lake's centrepiece: in the marked areas, shoes off (or in hired overshoes), step into water no deeper than your ankle over firm, gritty salt — it digs into the soles, so go slowly. Stand still, let the ripples settle, and the ground beneath becomes one whole mirror — clouds under your feet, your shadow beside you; queues for the picture are part of the deal. For a good reflection: get away from the crowd, shoot when the sun is low (before ten or after four), and wear bright colours. Salt stings cuts — stay out of the water if you have any; and the midday ultraviolet is fierce, painful within half an hour.

中午在服务区吃简餐：面片（青海人叫「面片儿」，揪出来的小面块煮汤）、炒面、酸奶，别指望大餐。饭后可以看景区里的盐文化展：茶卡从汉代就开始采盐，古称「卢溪」，盐走丝绸之路和唐蕃古道；近现代用铁轨和小火车运盐，老照片里一车车的青盐就是从这里发往全国。展不大，二三十分钟看完，刚好避一避中午最毒的太阳。

Lunch in the service area is simple: mianpian — small torn dough pieces boiled in soup, a Qinghai staple — fried noodles and yogurt; do not expect a feast. After eating, see the salt heritage exhibit: Chaka has been harvested since the Han dynasty, known in antiquity as Luxi, its salt travelling the Silk Road and the Tang-Tibet route; in modern times rails and little trains carried it, and in the old photographs wagons of green salt leave here for the whole country. The exhibit is small, twenty to thirty minutes — enough to shelter from the worst of the midday sun.

下午四点以后太阳开始往下走，角度低了，影子长了，水面上的倒影反而比中午更清楚，这是拍「天空之镜」的第二个窗口，很多人上午挤，其实下午这段更好。观景台在湖边高处，能看清盐田一格一格的纹路，那是一块块采盐留下的池子。体力够的话可以再下水走一次，这回拍照的人少多了，风也常常比上午小。看天气预报，明天要下雨的话湖面第二天会浑。

After four the sun sinks, the angle lowers, shadows lengthen, and the reflections sharpen beyond what midday gives — the second window for the mirror, and most of the crowd pushed through in the morning. The viewing deck stands high on the shore and shows the salt pans laid out in squares, the pools left by harvesting. If your legs still work, wade a second time: far fewer people, and the wind is often softer than in the morning. Watch the forecast — rain tomorrow means a clouded surface the next day.

茶卡的日落很正：太阳贴着地平线往下掉，没有遮挡，湖面先是金色，再变粉、变紫，最后天暗下来，盐湖安静得像睡着了。高原日落晚，夏天要到八点半到九点。看完日落气温掉得快，外套立刻穿上。景区晚上出园有末班交通，看好时间别为一张照片误了车。回镇上路上没路灯的地方多，慢慢开。

The sunset at Chaka is a clean one: the sun drops straight to the horizon with nothing in the way, the lake turning gold, then pink, then violet, before the dark comes and the salt lake lies still as if asleep. On the plateau the sun sets late — half past eight or nine in summer. The temperature falls fast afterwards, so put your jacket on at once. There is a last shuttle out of the reserve — check the time and do not miss it for one more picture. Much of the road back to town is unlit; drive slowly.

镇上的饭馆做的都是青海菜：手抓羊肉（白水煮的羊肉蘸椒盐，肉好就香）、酿皮（厚厚的凉皮拌辣子醋，青海人的凉菜）、炕锅羊肉（羊肉和土豆在铁锅里炕得焦香，分量大）、牦牛肉干、甜醅（燕麦做的甜酒酿）。盐湖玩一天出汗多、风又大，晚上早点吃、早点睡。镇子海拔三千一，晚上别喝酒太多，高原上酒劲上得快。

The town's restaurants all cook Qinghai: hand-grabbed mutton (boiled plain and dipped in salt and pepper — good meat needs nothing more), niangpi (thick cold noodles dressed with chilli and vinegar, the Qinghai cold dish), kang-pot mutton (mutton and potatoes seared in an iron pot until crisp-edged — a big portion), yak jerky and tianpei, a sweet fermented oat dish. A day at the lake means sweat and wind, so eat early and sleep early. The town is at 3,100 metres — go easy on the alcohol, which bites harder at altitude.
