Cache la Poudre

A lovely piece of work that deserves the widest possible audience, as biologists Howard and Mary Alice Evans describe and explain the natural history of the Colorado river and its plant and animal denizens from its origins in the tundra of Rocky Mountain National Park, through 80 miles and several life zones, to where it finally joins the South Platte just east of Greeley. Includes bandw photographs and line drawings. Annotation copyrighted by Book News, Inc., Portland, OR
