  • In the Northwest U.S. a coulee is a gulch carved out of basalt rock by the great Missoula Floods: A dry canyon eroded by Pleistocene floods that cut into the lava beds of the Columbia Plateau in the western United States. These coulees have steep sides and never were stream beds. The Grand Coulee in Eastern Washington State is the largest and best known.

  • "He heads off down a small coulee, staying hidden until he is on the far side of the cattle, trots right to pull in the herd, back left to tighten the flank, and moves in expertly from behind to push them forward. More than a hundred and fifty years of inventive selective breeding has created the perfect cowpoke on four legs. Gary watches his partner at work, always amazed that a dog with no formal training knows instinctively from an early age exactly what has to be done."
