Where on Earth - March 2015

Clues for March 2015:

1. This narrow, 19-kilometer-long gorge is the namesake feature of the national park that surrounds it and is located near the east coast of a lush, tectonically active island — to which multiple nations have laid claim — roughly 150 kilometers off mainland Asia.

2. Layers of marble (and other metamorphosed rocks that originated as seafloor sediments) comprise most of the bedrock in and near the gorge and are thought to have been uplifted and tilted into mountains beginning about 70 million years ago in a collisional tectonic setting.

3. Popular tourist activities include a trip through the "Tunnel of Nine Turns" (seen here) to view the most dramatic portion of the gorge, and rafting along the river, which continues to incise the canyon.
