It is a hideous photo shot. I see where the zr1 spyder is at. It is 80% buried with just the left rear poking out. That dirt is heavy and I am sure it has done lots of damage. Hate to see these pics actually. I am just glad mine is not in there. It just makes those callaway zr1 spyders more valuable.

A C4 with an OEM LT5 is a ZR-1, a C6 with an OEM LS9 is a ZR1. Nit picky yes, but an important detail as I was "taught" when I 1st joined here.

Anybody watching the live feed?
Bunch of guys in yellow vests moving transits around, but not much happening.

Re: Corvette Museum
 

I am guessing here but..........I bet those underground caves have everyone in that area wondering who is next. Time to change some construction site inspection rules at the State level (Pre and Post construction). And time to apply new technology to identify and monitor these underground caves.

Re: Corvette Museum
 

I noticed that too there.

Pretty cool job - standin' around and watchin' vettes, and gettin' paid for it.

Kinda' like bunch of guys standing around the back of a pickup truck, hangin' on the sides, lookin' at nothin' in the bed.

Or standing around a camp-fire, watchin' the flames burnin' up.

Just my thoughts......

I don't disagree with you and the technology is more than likely( basically geophysical seismic acquisition like we have used in the oil & gas industry for decades only now much more advanced and no "dynomite").

The problem in Karst areas, lies in knowing just how deep and large the "vug" (underground open area) is plus the overlying rock stress characteristics. Vugs & caves may take from hundreds to millions of years to form, depending on the amount of groundwater and resistance of the rock to solubility & erosion.

The roof collapse of a vug or cave may occur from a few feet thick to dozens or more feet. The roof collapse is not always "right under the surface" as it looks afterwards. The collapse may occur tomorrow or hundreds of years from now. There are so many variables that only the most eminent conditions might warrant preventative measures. So, what do you do if you detect a void space, say 112ft from the surface with only an approximation of rock overburden thickness, area and fracture strength, and empty or full of water? Avoid, build, pier, etc....?

To me, it's a bit like forecasting tornadoes. We are getting better, but seldom do we know exactly when or where until it happens. The certainty is only mother nature knows and ultimately she always has her way.

Good thing they don't have shovels to lean on. Yet.

Re: Corvette Museum
 

They were running survey equipment just now.
I wonder if it's still moving?

Re: Corvette Museum
 

I thought so too for a minute there - but early and current photos don't show enough to tell there...

Re: Corvette Museum
 

I don't know. This crack seems to be getting bigger from my past observations.
