[RE-wrenches] Grounding system for a shack on a frozen lake?

[Exeltech]

First .. why are you grounding a portable system?  It's not required.

In [29 CFR 1926.404(f)(3)(i)], OSHA states the frame of a portable
generator need not be grounded (connected to earth).

If it's a fuel-powered generator, the NEC 250.34 states the frame may
serve as the ground as long as normally non-current-carrying metal parts
of equipment and the equipment grounding conductor terminals of the
receptacles are connected to the generator frame. 

This is even more applicable if the system is all low-voltage DC only.
