摘要

This study is one of a series of 61 which cover the natural regions of the United States, defined largely be Fenneman (1928). Each study describes the ecological and/or geological features characteristic of that region, then evaluates sites representative of the various features. Sites which are outstanding examples are suggested as potential National Natural Landmarks. This report describes 155 sites of ecological significance in the Northern Rocky Mountains natural region, including areas in Idaho, Montana, and Washington.
