Geologic Tour in the Zemplén Nature Reserve
As part of National Geotop Day, explore the geological treasures of the Zemplén. These formations attest to the active volcanism of the area millions of years ago. The tour is lead by a professional geologist. Hiking boots are recommended.
The 300-meter high hill dates from the geologic Tertiary period, and was created during through volcanic processes during the middle Miocene. The hill is predominantly pumiceous and silicified rhyolite. The hard, crystalline rock was very practical in the production of mill stones since the XV. Century. Manufacture decreased during the 19th century until the quarry was closed in 1907. Until that time, 300-450 handmade millstones had been made annually. A rise in the water table in 1844 led to water collecting in the Medieval quarry area found in the southwest corner. The abandoned quarry eventually formed a lake, and the area and the lake were a declared nature protection area in 1997.
