The Northern Rockies
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.
Dimensions: All map dimensions are approximate.
