Landforms of the Northern Rockies - Fine Art Print Map
The deeply glaciated Canadian Rockies are strongly marked by a general
pattern of northwest - southeast arcs that extend through western
Montana, much of Idaho, and on into Wyoming and even Colorado. Rivers
are shaped by these trends, but also reinforce and emphasize them. The
Columbia, Kootenai, Clark Fork-Pend Orielle are notable examples.
Rivers of the mid-continent (Athabasca, North and South Saskatchewan,
Missouri-Yellowstone) develop the classic dendritic (tree-form) pattern
once they extend beyond the mountains. Wyoming’s Great Divide Basin,
along with Yellowstone and the Snake River Plain (see notes with the
Pacific Northwest) make a very rough but convenient southern boundary of
the Northern Rockies.
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.
