Chilla Wildlife Sanctuary, India

Chilla Wildlife Sanctuary, India

As it descends from the Siwalik Range in the Himalaya onto the plains of northern India, the Ganges River passes through the city of Rishikesh, an ancient site of Hindu pilgrimage. The river also passes through the Rajaji National Park, a network of wildlife sanctuaries covering some 820 square kilometers (320 square miles).

On November 27, 2009, the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this true-color image of the Ganges flowing through the eastern portion of Rajaji National Park, as well as the northern reaches of Rishikesh. As it passes through the city, the river appears to widen and curve a little more than it does in the nearby hills. East of the city, a canal diverts some of the river’s water (image lower left).

The Chilla Wildlife Sanctuary, one of the wildlife sanctuaries in the national park, is outlined in white, and its northern perimeter loosely matches the course of the Ganges in this area. Thick forest carpets much of the sanctuary’s rugged terrain, particularly near the Ganges River. On the hills near the eastern perimeter of the sanctuary, vegetation is sparser.
