Small abandoned quarry at the top of the Hradisko hill near Rožná village. This is the first opening of Rožná Li-pegmatite vein, where lepidolite is TL. Whole vein is over 1km long and has another outcrop on the top of the Borovina hill and some relicts could be found on the nearby fields.
Quarry was first mined for lepidolite in 19th century and during WWI. After 1919 mining was stopped and revived only during WWII for short mining of feldspar and quartz.
Locality is now abandoned and open for public collecting. Because it is well known, the site suffers from heavy load of collectors every year and therefore good specimens are more and more rare.
26 valid minerals.
