The Grande River flows from northwest to southeast, tumultuous for three thousand kilometers, crisscrossing nearly half of Central Northwest North America. The numerous water systems extending from this fifth-longest river in North America nourish hundreds of thousands of square kilometers of grasslands, millions of wild buffalo and deer, and hundreds to thousands of large and small hunting tribes.
To the various tribes of Coa Wei Ke in the lowest reaches, it is the motherly "Bravo River." In the mouths of the Concho tribes slightly downstream, it is the "Concho River" that birthed tribes. This long river pathway for two thousand kilometers downstream is precisely the natural border dividing the United States and Mexico in later generations.
