In 2014 I dug a new hole in my existing Eddy bed. This time there are many egg in an egg thundereggs. Sometimes with geodes too.
In 2015 and 2016 i continued following the thunderegg flow. But we are realy close to the borders of this interesting location

Ofcourse these teggs also available for you as collector: Uncut or cut & polished specimen !
So also possible to cut your own beauty.
