MLRA 44 - Northern Rocky Mountain Valleys Idaho, Montana, and Washington 32,320 km2 (12,480 mi2)

Elevation and Topography:
Elevation ranges from 600 to as much as 2,100 m; the highest is in south western Montana. The deep valleys bordered by mountains are mostly north-south trending. In the valleys, nearly level, broad flood plains are bordered by gently sloping to strongly sloping terraces and fans. In many places the valleys have been modified somewhat by glaciation, and in the north, lacustrine sediments cover much of the valley floors.
