I've got a far, far better solution I think, much more practical.

Require anyone intending to climb the mountain to register, and show proof of posting a $1 mil bond against the possibility of needing rescue.

That way if something happens, your fault, their fault, nobody's fault, at least the rescue attempt(s) get paid for by those who took the risk, and not by the gen pub. That seems much more responsible to me.

Can't get bonded or insured? Fine, then post the amount in escrow from your own account. Haven't got the $1 million up front, then don't take the risk. I grow tired of being forced to bail others out for their foolish or reckless behavior.

The alternative is to close the mountain down, then climbers will become trespassing criminals, or to abolish funding SAR with tax dollars.

Pick one.
