Hallikivi (Hallikivi)

Grey stone. According to TT: after a large erratic boulder nearby, but hard to locate. The Estonian Environmental Agency lists 5 Hallikivis in Estonia (infoleht.keskkonnainfo.ee), but none in Tallinn, while KNAB gives coordinates for a Hallikivirand (beach) on Aegna and there does look like a boulder at ///scenting.clinch.abbeys. But is it grey? To be confirmed. The things that keep you up at night!... See also Kivi. For other erratic-themed locations, see Kari.
