Valeč
Famous locality for opal-AN (hyalite) exploited since the 19th century. The specimens from this locality are part of many world museum collections.
The location was first mentioned in literature by Zippe (1823).
The best specimens of botryoidal opal-AN aggregates are from loose boulders of leucitic tephrite surrounded by clay.
The site was turned into a military area after WW II. The Czechoslovak and then Soviet Army were discouraging from mineral collecting.
Nowadays (2009) the site is still a military area, but access during the day and outside planned military exercises is possible. The site is also a nature preserve.
Currently the best place to collect is the summit plateau of Jedliny hill. Former sites exploited were on the hills of Doupovské hory N, NW and W from Valeč: Filíř (Pilíř), Číhaná, Kopáčov, Šibeniční vrch, Malý a Velký Hlavákov (Hlavákovský vrch).
