I read on another post that there is a huge concern about punctured oil pans and the oil spill they may create if there was a rock course at the St. Helen scramble area and have a few thoughts.
Is there some kind of liner that can be used to stop the oil from flowing into the earth? They put something down to under landfills. There is probably some kind of drainage system to let the water out and keep the oil in.
Why not dig a big hole, install the drainage system, line the hole with the liner, fill the hole with Sand, Gravel, Jello or whatever to use as a prefilter and arrange the Rocks on top of that. This way the oil can't escape and maybe a costly study can be avoided.
I bet someone knows someone who knows something about this type of system.
I know this is way more complicated then what I described but I wanted to get my thoughts out there. Maybe something good will come out of this idea. Maybe not.
