The dislocation at the foothill of the Ore Mountains with the largest coal basin nationwide stretches like a ravine between the forested slopes of the Ore Mountains and the young eruptive rocks of the Bohemian Uplands. Coal mining fundamentally affected the countryside in the region. By opening opencast mines the environment was considerably and irrecoverably affected. A number of municipalities and hamlets have gone, first near Všebořice, the municipal neighbourhood of Ústí nad Labem. The first villages to disappear from the map were Varvažov, Úžín, Roudný, Kamenice and others. The tram track from Ústí nad Labem to Telnice has been lost as well. Another turning point came with the opening of the giant Chabařovice mine in 1976. It was another brutal attack on the countryside and life of the locals. Further villages disappeared – Vyklice, Tuchomyšl, Hrbovice, Český Újezd and others. And then, Chabařovice looked to be next. In the late 1980’s demolitions started even there. However, unprecedented pressure from villages after 1989 stopped the plans of mining companies and Chabařovice was saved. The area of the former mine is being flooded these days, which shall create Milada lake and a future recreation resort. The basin only has a few striking hills i.e. the long Střížovický Hill (342 m), Jedlová Mountain (382 m) and Horka Hill (313 m) in Chlumec.
