The Geological Significance of Kyrgyzstan

 

Nick Coe is the Content Creator for the 2023 Silk Route Cycling Expedition. Inspired by the incredible scenery in the little visited country of Kyrgyzstan, he takes a look at its geology.

Nestled in the heart of Central Asia, Kyrgyzstan is a country of unparalleled natural beauty and diversity. While its stunning landscapes and vibrant culture have been captivating travellers for centuries, the geological significance of Kyrgyzstan often goes unnoticed. From towering mountain ranges to ancient rock formations, the country’s geology tells a tale of tectonic turmoil, ancient oceans and forces that have shaped the Earth’s surface over millions of years.

As TDA riders cycling the ancient Silk Route, we get to witness the geological aspects that make Kyrgyzstan a remarkable destination for geologists and nature enthusiasts alike. At the core of Kyrgyzstan’s geological story lies the ongoing collision between the Indian Plate and the Eurasian Plate. This collision is responsible for the creation of the awe-inspiring Tian Shan mountain range, often referred to as the ‘Mountains of Heaven.’  The immense pressure generated by the plates’ convergence has uplifted these mountains to staggering heights, with numerous peaks reaching over 7,000 metres.

“It is over 2500 kilometres across, the biggest crash zone, smack together zone, however you want to call it on the planet, and we’re in it,” stated Warwick, a geologist and rider from Vancouver. The meeting point of these tectonic giants is known as the Kyrgyz Tien Shan, a region marked by complex fault lines, fold-and-thrust belts, and active seismic activity. The effects of this ongoing tectonic action are evident in the numerous earthquakes that have shaped Kyrgyzstan’s landscape and continue to influence the region’s geology.

As I’m admiring a TDA campsite at the foothills of the Tien Shan mountains, Warwick describes the foothills we are nestled in. “These foothills are ancient! As the peaks go up and are unstable, they start eroding. They are growing faster than it is eroding.” This causes boulders to roll down the peaks, creating vast rolling foothills from landslides – like the one that we are settled in.

Lake Issyk-Kul, one of the world’s largest alpine lakes, also has a significant glacial history. Its formation was influenced by both tectonic activity and glaciation, creating a unique geological setting that has fascinated scientists and travellers alike. For us, it meant a fantastic swim, beautiful views and a pleasant camp backdrop. The lake has eight rivers running into to it and none leaving. It is the second largest saline body of water in the world and is believed to be fed by springs underwater (hot springs). The minimal amount of drainage also contributes to the high level of salt.

Kyrgyzstan’s geological significance is a captivating journey through time, marked by the collision of tectonic plates, the legacy of ancient glaciers, and the echoes of long-lost oceans. Its landscapes are a testament to the ever-changing forces that have shaped the Earth’s surface over millennia. As Warwick reminds us, “The mountains itself are much younger, but the rocks are ancient. The topography is young, the rocks are old.” While its natural beauty may take centre stage, delving into the geological wonders of Kyrgyzstan adds a deeper layer of appreciation for the intricate processes involved. Whether you’re a geology enthusiast, an intrepid explorer, a TDA cyclist, or simply someone curious about the Earth’s history, Kyrgyzstan’s historic mountains and landscapes are fascinating. An amazing backdrop to travel through.
