Today it reaches up 315 metres above sea level, but originally it towered 327 metres above sea level. Its 12-metre drop was caused by natural settling and erosion. The overall area of the slagheap is 82ha, and it contains more than 4 milion m3 of waste rock. The interior of the heap burns at 1500 ˚C. Thanks to this extreme heat, precious minerals, including jasper and porcelain can be found inside. The entire area is open to the public, and is marked by yellow tourist trails.
