Speaking of ground rods, the government has declared some (54 actually)
excess at this link:

There are some structural aluminum tubes in the lot right next to the ground
rods too.

solutions?
I have been reading the responses and have decided to try one last time to
get the rods as deep as possible. Last time around I rented a 20 lb Hilti
combination hammer drill/demo hammer. This time around I rented a 65lb
electric demo hammer -- a Hilti 3000. So I will attack the mountain tomorrow
and see what happens. I will be joining the rods together with 20 gauge 2"
copper strap so I think I will have quite a bit of contact with the soil --
just under 700 linear feet.
thanks for all your responses.

> I am finally getting around to putting up my 60' AN
Wireless tower on top of a rocky ridge in WV. I rented a Hilti demo hammer
and got about 1/3 of my rods in to the ground at least 4' -- but the
majority are only 2 or 3 feet deep because of the rocks/ledges. I don't
think I have much of a choice other than to cut the rods off and drive the
remnants into the ground field and exothermically weld my 20 gauge copper
strap to all of these shallow rods.
Other than paying big money for a well drilling rig to drill some deep 6"
holes and filling them with bentonite (which may not be possible given the
slope of the land and the fact that I now have 8 trenches running 75' out
from the tower pad) do I have any other practical alternatives?
Sure. The rods can be installed horizontally.
Cheers,
