Buštěhradská halda

Buštěhrad slag heap (Czech: Buštěhradská halda; 357 metres (1,171 ft) asl) is a huge artificial hill between municipalities of Kladno-Vrapice, Buštěhrad and Stehelčeves near Kladno in the Central Bohemian Region of the Czech Republic that have arisen in the late 20th century as a dumping site for slag from the Kladno ironworks, and other industrial waste. This is one of the most massive heaps of Kladno area, which, particularly when viewed from the northeast, forms by far the most visible and noticeable part of the landscape in shape of a mesa. The heap is situated less than 6 kilometres (4 mi) NE from the centre of the Kladno on right slope of shallow valley of the Dřetovický potok stream, in a place where borders of the three municipalities meet. Most of the heap (NE and central part) is based on cadastre of Stehelčeves. The southern part of it is on the territory of Buštěhrad town. Both these settlements lie within a few hundred paces from the heap. The westernmost part of the heap reaches the territory of the city of Kladno, specifically its suburb of Vrapice, just above the medieval church of St. Nicholas and municipal wastewater treatment plant. The heap covers an area of approximately 55 hectares and has shape of a trapezoid, slightly stretched on the south. Dimensions are 800 × 600 m, on a diagonal about 1 100 m. Its height varies depending on the surrounding terrain - from the southern side it is a little over 20 meters and on the north heap rises above bottom of the valley for nearly 70 m. The main, approximately trapezium body of the heap is extended vy a minor salient in the northwest in the northwest. This is the only active section of the heap at the present time. All the rest of the heap is no longer in use and so its overall size does not increase in any way. The core business of the heap, founded after the World War II, in 1950s through 1980s.
