The Himalayan valley is the geographical guard of the Indian territory against any foreign invasion keeping the enemy at bay from the western to the eastern subcontinent of the Asian sphere. The valley abounds with a classified variety of different glaciers, wildlife, peaks and thick vegetation liable to support the homo sapiens. Pindari glacier is a range of four glaciers, namely Sunderdunga, Namik. Pindari and Kafni. To go to Pindari glacier it is a 54 km trek and the walking part is normally covered in four days. In this trek, we cross many mountains and forests and see a lot of wildlife. We were eight members in the team. The whole trip took us ten days in the mountains. Throughout the way, our guide and my father explained to us the various features of the Himalayas we were passing through. We had to face bad weather for two days. There was a steep climb at some places and as we climbed up we were affected by high altitude sickness and lack of oxygen and we felt very tired. Pindari glacier is surrounded on all sides by snow-covered peaks such as Nanda Devi, Nanda Kot, Nanda Khat, Bailiuri and many more.
