Bluestone Introduction: The main landscape of the Bluestone Scenic Area is a tectonic relic formed by crustal movement. People often use "rock-solid" to describe the stability of the earth. In fact, the crust under our feet is in constant motion. For example, the collision between India and Asia half a million years ago caused the Himalayas to rise from the ocean and become the roof of the world. ; The bluestones and flower stones produced in the bluestone scenic area are famous garden ornamental stones in Southeast Asia. These rocks are caused by the force of crustal movement.
