The Aru Basin catchment (black boundary), with Aru Lake (lower) and Memar Lake (uper) and 6,000 m Aru Mountains forming its western boundary. Fences constructed within the basin in 2006 and 2007 are shown as short lines or rectangles. The southern end of the basin is an important wintering and spring migration staging area for Tibetan antelop (oval), and the antelop migration routes through the basin are shown, with line thickness signifying importance.

This core of the earth This heart of the world

Fenced round by snow The headland of all rivers

Where the mountains are high and the land is pure.
