The bowels of the Allegany Plateau are rich in coal deposits, and the coal horizons have a large extension and a shallow depth. Often rivers reveal coal-bearing strata, which facilitates the open-pit mining of coal. In the same areas, for the first time in the country, (nowadays heavily developed) deposits of oil and natural gas were discovered. In the north, the plateau comes very close to Lake Erie, leaving only a narrow strip of lakeside lowlands. In this part of it there are many lakes, which, due to their unique shape (narrow, elongated from north to south), are called finger lakes. Lakes formed on the site of the beds of ancient rivers backed by a glacier looming from the north. Protected by the surrounding hills, the valleys of the lakes have a mild climate, and fruit crops and even some grape varieties are successfully grown in them.

In the United States, five major geographic regions are distinguished: three in the main territory (East, Inland Plains, and Cordillera Mountain Country) and two separate — Alaska and Hawaii. The eastern region includes the ancient mountain system of the Appalachian mountains and coastal lowlands along the Atlantic Ocean and the Gulf of Mexico. The Appalachian mountains stretch from north-east to south-west at a distance of more than 2.5 thousand km. At an average height of 500-600 m above sea level, many peaks reach 1800-2100 m. The northern and southern sections of the mountains differ markedly. The northern Appalachian mountains, subjected to ancient glaciation, are reduced, divided into a number of mountainous areas, divided by wide river valleys processed by the glacier. The Hudson River, with its tributary Mohawk, outlines the Adirondack massif, whose elevated eastern edge abruptly breaks off to the Hudson valleys and Lake Champlain. Composed of crystalline rocks, dissected by narrow gorge-like valleys of numerous rivers, Adirondack is unsuitable for economic use. Its steep slopes, often covered with stone placers, are overgrown with coniferous forests; a significant part of the territory of this mountain range has been turned into a nature reserve. The northeastern part of the Appalachians is represented by a mid-high plateau, on which separate stop mountains rise. In winter, the mountainous areas of the Northern Appalachians are covered with dense snow cover. On Saturdays and Sundays, many tourists and skiers come here; in the summer, the forests of the North Appalachians serve as a place of rest and hunting. On the slopes of the mountains grew resort villages and sports facilities. In river valleys on alluvial deposits of which fertile soils have developed, farmers are engaged in agriculture. The Southern Appalachians, in contrast to the Northern Appalachian Mountains, are a more cohesive mountain structure affected by ancient glaciation only in the far north. Their western foothills form the Appalachian (Allegan and in the south of Cumberland).
