The chemical character of the summit ecosystem is expressed, diluted and distributed, in the rivers that water the lowlands for hundreds of kilometers below.

The Other Tepuis And What They Tell Us

Roraima is the most famous of the tepuis, but understanding it fully requires seeing it as part of a larger system — an archipelago of sky islands that together constitute one of the world’s most distinctive biogeographical regions.

Auyan-tepui is the largest of the tepuis by summit area — a massive plateau covering approximately 700 square kilometers, with a perimeter of cliffs that make Roraima’s seem modest in comparison.

It is most famous as the source of Angel Falls / Kerepakupai Merú, the world’s highest uninterrupted waterfall, which drops 979 meters from a notch in the tepui’s rim.
