-just purchased my copy of 3D World Magazine Issue 103.  --has a great DAZ temple ruins for Poser 5 ++ and a Bryce.  The ruins come in parts and can be downloaded in Poser's root directory via Runtime or in a separate folder.  It has pillars broken walls, arches, statues, rumble etc.  Each part has subparts that you can delete.

There is a Bryce  tut on how to make an underwater scene.  However, it can be applied to Poser 5 plus as well. 

There is also a city scape and a 1920's type hotel etc contained on the CD (not a DVD) also.

DVD:  made that mistake once before (I don't have a DVD).  Jan
