Our campus sits on a hill. Every time it rains heavily, rainwaters will gather together to form a stream. From the center of the campus, the stream flows through the Sullivan Road, all the way down to the foot of the hill. The gathering surface water on our college hill reminds me of the way many rivers form. Mostly, the headwaters of rivers originate at marshy areas fed by mountain snow. In class, we discussed some rivers that begin their life as tiny streams running down a mountain slope. For example, the polluted holy river the Ganges starts as a little creek in the western Himalayas; the Yangtze River originates in Tanggula Mountain in the west of China.
