The most prominent object that is reflected above the water surface is a cliff from a karst hill in the middle of a tropical forest. The cliff looks like a solid natural wall. Below it appears groundwater and forms a fairly wide spring, and becomes the headwaters of a river which then empties into the sea. The very clear water source reflects the surrounding wilderness which is filled with various vegetation besides the extraordinary cliff walls. This location at least represents the atmosphere and condition in the middle of tropical nature in Sumatra.
