The Northern Rockies Fine Art Print Map 
The map is centered just north of Yellowstone. The headwaters of much of
 North America’s river systems meet here: The Columbia-Snake, the 
Missouri, and the Green River portion of the Colorado. The North and 
South Saskatchewan rise one narrow ridge east of the Columbia.     
The Northern Rockies regional map covers all of Idaho, Montana, and 
Wyoming. Neighboring portions of British Columbia, Alberta, 
Saskatchewan, the Dakotas, Colorado (a sliver), Utah, Nevada, Oregon and
 Washington are also shown.
