To me, this is on a par with pouring millions of dollars into beach restoration on the Atlantic Coast of the U.S.
That site has been open for decades and we have gleaned much knowledge from it. We should continue to glean such knowledge while we can. But to pump money into it to preserve it from weather?
Is it not due to the vagaries of weather, or perhaps more accurately, the natural forces of geology, that it was "preserved" to us in the first place?
