• The Siachen Glacier is located in the Himalayas’ Eastern Karakoram range, slightly northeast of Point NJ9842, where the Line of Control between India and Pakistan terminates.
• It is the world’s second-longest glacier in non-polar locations. 
• The Siachen Glacier is located just south of the major drainage divide that divides the Eurasian Plate from the Indian subcontinent in the heavily glaciated section of the Karakoram known as the “Third Pole.” 
• The Siachen Glacier is located in Ladakh, which has recently been designated as a Union Territory. 
• The Siachen Glacier is also the highest battleground in the world. 
• Operation Meghdoot –1984, was the first attack undertaken in the world’s highest battlefield, resulting in Indian soldiers capturing control of the whole Siachen Glacier.
