Field Notes from East of the Rockies

Wander Laurentia

Laurentia is everything east of the Rockies, from the Great Plains and Canada's prairies to the bayous and the Atlantic — a vast, emptying heartland reshaped by climate change and industrial agriculture. Follow me down its lonely roads, from Minnesota to Louisiana.

Why Laurentia?

Everything East of the Rockies

Strictly speaking, the Great Plains are the grasslands that roll east from the foot of the Rocky Mountains, from the prairies of Alberta and Saskatchewan down to the Texas Hill Country. Short grass in the rain shadow of the mountains gives way to mixed and then tall grass as the land drops and the rain comes in. Somewhere near the Missouri, the plains become the Midwest.

Laurentia is the whole of that downhill run: everything east of the Rockies. It takes in the farm country and lakes of the upper Midwest, the great Mississippi basin that drains it all, the bayous and swamps of the Deep South, the old worn-down Appalachians, and the Atlantic seaboard where the continent finally ends. The name comes from what lies beneath most of it: Laurentia, the ancient stone core, billions of years old, around which North America was built.

  • 100thmeridian, roughly where the rain gives out and the dry West begins
  • 41%of the contiguous United States drains into the Mississippi
  • ~4%of the original tallgrass prairie still standing
  • 21%of the world’s surface fresh water, in the Great Lakes

From the Plains to the Atlantic
