The Conglomerate of Cushendun

 

Not the name of one of the minor princes in Game Of Thrones, this refers to the geological material,  clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts. In this case, it's specifically the outcrop near Cushendun, in Northern Ireland.

Actually, it is reported that Cushendun Caves was used as a filming location for Game Of Thrones. Interesting.
