Ardennes
Ardennes is part of the Ardennes, a plateau deeply cut by the Meuse and its many tributaries which reach into Wallonia in Belgium, Luxembourg, Germany (Eifel), and the north of the neighbouring department of Meuse.
Covering , the department was the smallest among the four contributors to Champagne-Ardenne. It is diverse in climate, topography, natural vegetation and land use, which is a mixture of forest and arable farming.
The highest point is 504 m, on the southern slopes of the Croix Scaille shared by French commune Les Hautes-Rivières and the Belgian commune of Gedinne.
It is in this part of the Ardennes mountains or high hills that the Meuse winds through, known locally as "the valley". Flowing into the northern part of the department, it waters the main cities of Sedan, Charleville-Mézières, and Nouzonville. It has numerous tributaries – the main ones locally being the Semois and the Chiers.
As to the south, the Aisne flows through the vast near-treeless plain of Champagne chalk (historically by the landed class and bourgeoisie disparaged as flea-ridden Champagne) extended to the south-west by the small, grain-growing Porcien, Thiérache in the west and Argonne in the east are fringe grasslands with very distinctive upper soils.
