The divide

River head waters may be separated by only a few meters along the Continental Divide of North America. Consider the Columbia River that flows into the Pacific Ocean and the Missouri River that flows into the Atlantic Ocean. Although they begin very close to each other, they eventually flow through different landscapes, through different cultures, making them very different rivers.


This series is a photo essay on these two major watersheds. Here we begin with head water springs. Water that flows up from below ground to form the start of a river.

Some rivers begin with head water lakes.

Small streams flow into larger streams.

Larger streams flow into rivers and lakes.

Eventually into the large, main stem of the river.

Before flowing into the ocean.


Tethysphere will profile parts of each watershed over the weeks to come in a celebration of rivers!
