The territory of Idaho is divided into four natural regions: the northern region of the Rocky Mountains, the central region of the Rocky Mountains, the Columbia Plateau, and the Great Basin region to the west. The state’s average elevation is approximately 1,500m above sea level, with the highest point being Mount Borah (3,859m).

The northern part of the Rocky Mountains occupies the central area of ​​the state, and the strip of land between Montana, Washington and Canada. This is an area of ​​steep mountains and lakes formed by glaciers thousands of years ago. The central section of the Rocky Mountains occupies a narrow strip of land along the Wyoming-Idaho border. This region includes the southern mountains, including the Wasatch and Bannock Ranges, interspersed with lakes and valleys full of cattle grazing. Along this section of the Rocky Mountains lies a triangular-shaped region, whose base is the border between Utah and Idaho, and which forms part of the Great Basin of the Western Cordillera of the United States.

The largest of Idaho’s rivers is the Snake which originates in northwest Wyoming, in Yellowstone National Park. After traversing the south of the state, it flows into central Idaho and wedges into the Seven Devils Mountains that form the eastern frame of the Snake River’s Grand Canyon, with an impressive section known as Hells. The Snake River receives the waters of the Salmon and Clearwater Rivers which flow parallel to the Snake, from the west to the north central state. Other important rivers, which flow in the northern part of the state, are the Saint Joe, the Coeur d’Alene, the Pend Oreille, the Kootenai, the Payette and the Boise. Idaho is a land of lakes; between about 2.

Flora and fauna – About 40% of the state’s surface is covered by conifers, while half of the remainder is made up of pastures.

Large animals include deer, moose, goats, antelope, panthers and bears. Many species of small animals live in mountainous or desert areas.

The climate – Idaho is very diverse, due to the diversity of its territory. Temperatures in summer are mild with averages between 21 ° C and 24 ° C in July, while in January the average temperatures oscillate between -1 ° C and -9 ° C. This is because the north-west area of ​​the territory receives the temperate and humid winds of the Pacific, while the eastern mountains normally avoid the arrival of excessively cold winds from Wyoming and Montana. Precipitation is irregular, with annual averages of 254 mm in the Snake River Plain, and 760 mm in the northern region of the state. Precipitation in the form of snow is abundant, especially in the upper part of the mountains, with annual averages of more than 500 cm.
