Why things happen, drawn on a map
Each story is a short, guided flight over the atlas: one geographic fact per step, every claim graded and sourced. Read in order or jump around — the map moves for you.
AFRICA · THE ESCARPMENT PROBLEM
The Rivers That Don't Connect
Africa has some of the mightiest rivers on Earth and almost no river trade. The reason is a step — and it shaped everything.
THE UNITED STATES · THE GEOGRAPHIC JACKPOT

The United States is powerful partly because it won a lottery drawn on a map — two ocean moats and the best river-and-farmland overlap on Earth.

RUSSIA · THE NORTHERN EUROPEAN PLAIN

The world's largest country behaves like a besieged one. The reason is flat, and it runs from France to the Urals.
