Guild Wars 2

Hey guys so I’ve been powering through the collection to get my first ever legendary but there is one collection piece that is giving me hell. In Southsun Cove I have to use a glacial imbued jar at a place where water is cascading from pools. I have been trying to do this for about a hour and its crazy annoying the entire map is mineral pools yet none seem to work. If anyone has done this collection before please help a player out. Thank you

You get it at a waterfall right below the “glass” part of “Driftglass Springs” if you look at the map.
