If you have a problem with a ground due to terrain issues, you might want to look into using Lyncole grounding rods. These are hollow copper tubes with a chemical crystal compound inside. The rod has some tapes around breather holes which you remove prior to burying in betonite clay etc.. The top of the rod is left just above ground in a round housing / inspection cover. These create temperature differential between top and bottom and create moisture condensation which leaches out and creates a better ground over time. There is also a L shaped grounding rod which is laid in a trench in case you can't dig down 8ft or so. Usually only one or two rods are required to achieve the 4 ohms.
