Cell phone "walkie-talkie" requires a cell tower as I understand it.

I've used several of the motorolla type walk-about machines with15 or 20
channels, and 30 some sub channels. They work well up to about 2 miles in the
mountains. I think the canyon would need to be tight and nasty to mess them up.
