What is ISO? And what is 'for the ground'? I get the granite bird path part, but that's all!

Ok, ISO is in search of and for the ground means it just lays on the ground, no stand. Just a carved rectangular piece of granite. I just found this but it's just a bit small but not bad and a good price too.

You could check out Swenson Granite. They are originally local to NH, but have a Newtown, CT store among other places in New England. We have been happy with the steps we bought there. While I don't see anything on the website that is exactly what you want, I am not sure if it is comprehensive or if they would sell you something like their pedestal birdbath without the pedestal.

java, I like the looks and size of that birdbath. Mine is smaller because it's more like the shape of the state of NH. Sometimes the birds will fight over it but generally they wait their turn in nearby shrubs and trees.
