After an hour’s flight from Kinshasa that included a breakfast tray of three kinds of stale bread and an equally stale cup of coffee, we landed in Mbandaka, a city that sits on the Equator where the Congo River no longer forms the border between the two Congos but instead sneaks inland a bit into ours. From here, the river continues north for awhile before starting its dramatic arc southwards. (Technically it flows the other way around — beginning in the highlands of DR-Congo and Zambia, semi-circling the country and exiting into the Atlantic Ocean — but I think you know what I mean.) Since it crosses the Equator twice, it’s always in a rainy season somewhere, making it second only to the Amazon in terms of flow rate. It drains into the Atlantic Ocean with so much force that it’s carved out a canyon below the seabed 1,000 meters deep, and fresh water can be found in the ocean 200 kilometers out.
