The Grand Canyon Council doesn't have an official home page yet. But I hear they are working on one. This page has some information about the programs in the council, like Silver Axe, the Grand Canyon Council's JLTC program.
If you need some information from the council or about the council, here are a few ways to contact them. I personally cannot answer your questions about troops or other council info.
Pending permission from the Grand Canyon Council, I will try to list all the districts and their DE's. Check back for more info.
