北方的空地，孤身穿越大羌塘无人区
Northern Empty Wilderness, Solo Traverse of No Man's Land in the Great Chang Tang

    第二次穿越大羌塘无人区已过三月，期间不少志同道合者询问事宜，今儿便呈一贴，简叙过往。
    
    此次穿越从青藏高原的西端至高点界山大阪开始，时间2010年4月20日，一路向东经邦达错、羊湖、若拉错、岗扎日，横穿整个藏北无人区后改由北上进入阿尔金无人区，经可可西里山脉、昆仑山脉、鲸鱼湖……在阿奇克库勒湖遇人，再三天车程至花土沟镇，时间七月五号，总历时77天。在离开界山大阪至阿奇克库勒湖的74天里独处无人区，此间行程1400公里左右，跨度四个月。

   【大羌塘】藏语“羌塘”意为北方的空地，狭义指藏北无人区，实则是所有北方未知的土地。大羌塘包含藏北无人区、可可西里无人区、阿尔金无人区、昆仑山无人区，这四个无人区连片在一起，构成了世界上独有的超级无人荒原。由于可可西里的概念被炒热，以至于大家一度用可可西里代替了这片广袤的荒原，实际上，可可西里不论是行政疆域还是地理疆域都只是大羌塘这片土地的一小部分。
    大羌塘，他是自由最后追逐之地……



It has been three months since I traversed the unpopulated region in the Great Chang Tang. There are many like-minded asking me about it. I now present this thread to briefly tell everybody about my journey.

The starting point of this traverse was from the highest peak of the western part of the Tibetan plateau, Jieshan Daban, and the day was April 20, 2010.  I was heading eastward passing Bungdag Co, Yanghu Co, Rola Co, and Kangzhagri Mountain, which crossed over the desolate region from west to east. The journey continued northward to enter the unpopulated area of Altun Mountains, through Hoh Xil Mountains, Kunlun Mountains, Whale lake, ..., finally met some people by the Aqqikkol Hu and then arrived in Huatugou by vehicle three days later and that day was July 5. It had been 77 days in total. I had been all alone 74 days after leaving Jieshan Daban until arriving in  Aqqikkol Hu, which was about 1400km and about four months.

[The Great Chang Tang] In Tibetan, "Chang Tang" means northern empty wilderness while narrowly, means unpopulated region in northern part of Tibet. However, it actually indicates all of the no man's land in northern. The great Chang Tang includes desolate places in Northern Tibet, Hoh Xil, Alun Mountains, and Kunlun Mountains, which are interconnected to form the unique and super empty wilderness in the world. Only because Hoh Xil is the most known name, most people just think this vast land is equivalent to Hoh Xil. In reality, Hoh Xil is only a small piece of the Great Chang Tang both administratively and geologically.

The Great Chang Tang, the last land to chase your freedom and dream.（treker）
