Ambraw

Ambraw is another name for the Embarras River, which rises in the Illinois prairie and flows south to the Wabash. French travelers gave it a name associated with obstacles to passage, such as fallen timber and tangled logs. The form Ambraw reflects the French pronunciation. The river crossed a route known as the Vincennes trace, which linked settlements on the Wabash with the Illinois country farther west; high water could make the crossing difficult for travelers.
