[3.5] My PCs have gone to the City of Glass in the Elemental Plane of Water. I can't find a map. Help.

In the course of events my PCs have ended up in the City of Glass and I can't find a map for it. I was wondering if any one has sometime made already or knows of some issue of Dungeon or Dragon that has one hidden in it. It doesn't have to be super detailed as I don't expect them to be there long but I never know with these guys.
