Chelab Valley: Aqtashtoq to the source of the Chelab Stream (trek)
Distance: 31km
Total Distance: 9001km
The true source of the Oxus/Amu Darya became a matter of conjecture almost 200 years ago during the Great Game when imperial Britain and Russia competed for control of Central Asia (as detailed in Blog 28).
Created in the late nineteenth century at the conclusion of the Great Game, the Wakhan Corridor served as a buffer between the territories of the British and Russian empires. The two empires agreed that the true source of the Oxus would mark the border between their territories. Several sources of the river were identified – Lake Zorkul (then named Lake Victoria by Lt Wood, 1858), the ice cave at the head of the Wakhjir River (discovered by Lord Curzon, 1893) and Lake Chakmaktin.
For over a century it was believed that Lord Curzon’s discovery, the ice cave at the head of the Wakhjir River, was the true source. But then, in 2007, Bill Colegrave led an expedition to visit and measure the ice cave and upon further exploration discovered that the ice cave was not the true source of the Oxus, rather it was the head of the Chelab, a small stream flowing down from the Nicholas Range (Named after Tzar Nicholas II during the Great Game). Unusually the stream bifurcates; the west-flowing branch enters the Little Pamir (or Bozai) River (which 15km later flows into the Wakhjir to become the Wakhan River and then joins the Pamir River to become the Panj River), the east-flowing rivulet ends up in Lake Chakmaktin (out of which flows the Aksu/Murghab/Bartang tributary that enters the Panj River at Rushan). The point at which the Panj River is joined by the Vakhsh River is the beginning of the Oxus/Amu Darya. This means water from the Chelab flows into the two main tributaries of the Oxus. Therefore, the source of the Chelab should be considered the true source of the mighty Oxus River.

However, while Bill had identified the Chelab Stream as being the true source, he had only been as far as where it bifurcates and encouraged me and my team – Rupert, Malang and Adrian – to follow the stream and its tributaries to discover the true source of the Oxus.
The plan was to start the trek from Aqtashtoq, a winter settlement belonging to the Kyrgyz clan who live and graze their animals in the region, including the Chelab Valley. It’s only about four kilometres from where I ended the cycle expedition and near to where the Chelab Stream bifurcates. At 4117m elevation, this is the lowest of their settlements where they live out the bitterly cold winters. Being the end of summer, the camp was empty apart from three men who were cutting and stacking slabs of dung, their essential fuel source, in preparation for winter.



After a stodgy lunch of 2-minute noodles (again) we ventured across the pamir (high plain) to the main summer camp. We needed to buy bread for the trek and it is always good practice to speak to and learn from the people of the land. Between the two settlements there was a rough track that crossed the smaller west stream (after the Chelab bifurcates) and stayed on higher ground – much of the pamir is swampy due to a network of tiny waterways, making the land surface very boggy.
En route we tried to locate the watershed, a higher point in the landscape where no water flows across it. The watershed determines the direction of the water flowing off it – streams on the west side of the watershed flow west, to the Little Pamir River, and streams on the east side flow to the east, draining into Lake Chakmaktin. It is a particularly important landmark relating to the bifurcation of the Chelab – the land feature that forms a barrier to the Chelab Stream and may have caused it to bifurcate. Due to the complexity of the landscape, including the conundrum of rivulets on the Little Pamir, the watershed is particularly difficult to define. We didn’t locate it exactly at the time but by studying satellite maps later, and with the team’s observations, I think I may have worked it out – if so, we were within 150m of driving over it. This needs further investigation before anything is published.


We were welcomed and had tea with the chief along with several other men from the community. One was a teacher on a four month stint (school is only in the summer months), who spoke reasonable English. Malang asked whether anyone from the local community had ventured up the Chelab Valley to the source of the stream. The chief said that while they use the valley to graze their yaks, sheep and goats, no one had any need or interest in following it to the source – above where the grass grows.
Back at Aqtashtoq, the donkey handler and his two donkeys had arrived. Malang had hired him in Sarhad. From there the donkey entourage immediately began the 80km trek. They started at 2.30am in order to make it in time the next day (40km a day on foot).

Day 145: Day 1 of the Chelab Trek
15th August
Distance: 10km
We set off at 7am from Aqtashtoq, the donkey man leading the way up the west side of the Chelab. There was a faint track for the first three kilometres leading to the community’s autumn camp. It is important for the Kyrgyz to keep their stock moving to new pastures so not to overgraze any regions. Judging by the lush grass in many places, the animals were not short of food.






After 6.5km we reached the confluence of the two tributaries that form the Chelab Stream. At this point we had to decide which stream to follow; which was the bigger stream. I had measured the length of both streams on Google Earth and, although things can look a bit different on the ground, I had at least ascertained that they were of a similar length and altitude; the west stream being about 300m longer.
Standing near the confluence, it seemed obvious that the west stream was the more significant waterway. It appeared as though the east stream flowed into the bigger west stream. It was a pity I couldn’t bring my drone into Afghanistan. That would have made our decision a lot easier.


We were all in agreement that the west stream was the one to explore. We followed the stream as it veered left and a kilometre later found an idyllic camp spot near the water.

We had planned to head for the source on the first day to give us the possibility of exploring the other tributaries the following day, but as a team we were too slow. Rupert was unwell and could not keep even half of our pace. With the waters rising in the afternoon due to the daily glacial melt, and time not on our side, we made the decision to head back to camp and get a very early start the next day. Before doing so, Adrian (filmmaker), who is a very strong trekker and mountain climber, crossed one of the bigger tributaries and did a recce to check what was ahead, at least for the next section of the valley. We especially wanted to know whether there were any major obstacles to negotiate.

Day 146 (Day 2 of the Chelab Stream trek)
16th August
Distance – 21km
Rising at 4am, breakfast, as had been the usual fare since Ishkaskim, included tea, bread (bought from the Kyrgyz community), long lasting cream cheese and jam. As Rupert hadn’t been able to keep up the day before, he offered to trek at his own pace, accompanied by the donkey man.











We took time to absorb the moment. Our silence was broken by the regular cracking of the nearby glaciers as they melted. In the warmth of the day, water literally poured off the Chelab Glacier into the lake. Small rivulets carved in the ice channelled the water into waterfalls. It felt very appropriate that we made this discovery in the International Year of Glaciers’ Preservation.
My emotions were very mixed. On one hand, I was very proud of my achievement, from taking an idea that I dreamed up to actually bringing a team to the finish line here at the true source of the Oxus. On the other hand I felt overwhelmed. I could feel this was a powerful place but this is also such a fragile, threatened environment. The small icebergs in the middle of the lake floated silently, precariously – their days numbered. Every year now, the glacier recedes a little more and the exact location of the source will change.
I felt aware that I was standing in a moment of time within the long history of the search for the source of the Oxus. I imagined, in the time of Marco Polo (13th Cent.) or the Great Game (19th Cent.), glaciers would have dominated the valley and the source would be in a vastly different place, further downstream. I dread to think of the days when there will be no more glacier left to melt. What will that do to the river and the lives of millions of people who rely on its waters? Eighty percent of the water in this river, and the Syr Darya, comes from glaciers.




When cycling around the Aral Sea I saw firsthand what happens to the environment when it is blatantly abused, and learned how the toxic dust doesn’t only affect the health and wellbeing of the local population, it has spread around the world, as far as Antarctica. This has become an issue that affects us all.
The source of the Oxus is clearly a special place. The alarming disappearance of this glacier, as with glaciers around the world, is a result of climate change; caused by human activities around the world, not by local and regional actions as with the Aral Sea. Whether it is local actions causing global problems or global actions causing local issues, we are all in it together. And together we must work to solve and manage these issues.
The historical and religious significance of both the Oxus (Amu Darya) and the Jaxartes (Syr Darya) rivers dates back to the teachings of the Prophet Muhammad who mentioned four rivers that are found in the paradise. These rivers, the four most important in the Arab world, are called Saihan (Syr Darya/Jaxartes), Jaihan (Amu Darya/Oxus), Euphrates and Nile. He mentions that each of these rivers have water that is pure and sweet to drink from. It is believed that these rivers will never run dry and will always be full of life-giving water for the people who inhabit paradise. This hadith (words from Muhammad) teaches people to strive for a place in paradise by doing good deeds throughout their lives so they can enjoy its blessings forever.
We did drink from the glacial streams of the Oxus/Jaihan/Amu Darya and the Jaxartes/Saihan/Syr Darya but nowhere else along these rivers is there water I could safely drink. There is the very real threat that these two rivers, with the accelerated melting of the glaciers in the Tien Shan, Pamirs and Hindu Kush, with the mismanagement of the water resources and with the compounding need for water by the growing populations, could run dry, or virtually dry. Doing good deeds to strive for a place in paradise has a very literal meaning in the case of the Aral Sea Basin.

We were aware that the 28 streams we needed to cross on the return trek were rising by the hour as the ice melted in the afternoon and hurried back to camp before it became too difficult, and then back to Aqtashtoq. It took over four hours to drive the 80km back to Sarhad and nine hours to drive the 192km from there to Ishkashim the following day, such is the state of the tracks and roads that I had endured on a bicycle.
Back in Kunduz we briefly crossed paths with Sophie Ibbotson and her friend/colleague Kamila Erkaboyeva who, by total coincidence, were heading out to explore the Chelab Stream in search of the true source of the Oxus! They explored the east branch of the Chelab and we hope to collate our findings to bring greater knowledge and understanding about this very special and remote region at the roof of the world.
