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 both shaped by and strengthen the trends. The Columbia, Kootenai, Clark Fork-Pend Orielle are notable examples. Great Rivers of the mid-continent (Athabasca,  North and South Saskatchewan, Missouri-Yellowstone) develop the classic dendritic (tree) pattern once they extend beyond the mountains.
