The Sia La ( German Sia Pass ) is a 5598 meter high mountain pass in the Karakoram . It connects the Siachen Glacier , flowing to the southeast , with over 70 kilometers of the longest Karakoram Glacier, with the Kondus Glacier, flowing to the southwest . The Sia La lies between the Saltoro Mountains in the south and the Karakoram main chain in the north, more specifically between the mountains Ghent Kangri (Saltoro Mountains) and Sia Kangri ( Baltoro Muztagh ).
Sia La is located in the historical region of Kashmir , the border with China runs over the summit of the nearby mountain Sia Kangri. Both India and Pakistan lay claim to the territorial administration of this area. As a result of the Kashmir conflict , which had been simmering since 1947, the 740 km long border between India and Pakistan was established in the Shimla Agreement as the so-called Line of Control (LOC) up to geocoordinates NJ 980420 ( ) as the easternmost point of the border. Pakistani and Indian authorities interpreted the further course to the Chinese border differently. According to Pakistani views, the Sia La is in Pakistan, as is the Siachen Glacier. However, India claims the main ridge of the Saltoro Mountains as a border, the Siachen Glacier is therefore Indian territory, the border runs over the Sia La.
This dispute led to the Siachen conflict between Pakistani and Indian armed forces in 1984 . In the course of Operation Meghdoot, the Indian army occupied the Siachen Glacier and the Sia La and also the Bilafond La and Gyong La passes , which allow access from the Siachen to the Kondus Glacier further south.
As a travel route, the Sia La is only of theoretical significance. The ascent from Kondus Valley to Sia La is extremely steep. The only pass ascents were made in 1979 and 1980 from the Siachen glacier over a high plateau on the south face of the Sia Kangri to the Conway saddle , which leads to the Baltoro glacier in the north, or in the opposite direction.
