NCM Sinkhole Update: Two More Vettes Visible; Rescued Vettes On Display

1991 Corvette Spyder National Corvette Museum Sinkhole 1/10

Three more to go! Markings (by the NCM) show where the 1,500,000th Corvette is, and a portion of the ’91 ZR-1 Spyder that was previously seen sticking out. Before they come out, there’s a big concrete floor slab that’s got to be removed first.

Wondering what’s been going on at the National Corvette Museum sinkhole? In our last report we covered the recovery of the eight Corvettes from the sinkhole that opened up under the Museum’s Skydome in February.

The latest pictures taken by the Museum show the 2009 1,500,000th Corvette, as well as the ’91 ZR-1 Spyder—which are still in the sinkhole—as crews prepare to lift a giant concrete floor slab, the next step in the rescue operation before those two Vettes—and the ’01 Mallett Hammer (a past GM High Tech Performance cover car) can be hoisted out of the sinkhole.

The five Vettes that were previously recovered from the sinkhole are on display in the National Corvette Museum until August 3.

In the meantime, the five Vettes that have already been recovered are now on display at the NCM in their “as-recovered” state: the ’62, the ’93 40th Anniversary coupe; the ’84 PPG IndyCar World Series Pace car; the ’92 1,000,000th Corvette; and the ’09 ZR-1 “Blue Devil.” They’ll be there through August 3, and then they’re slated to head up to Warren, Michigan, for their restoration at GM Design’s prototype shop at the GM Tech Center.

Finally—we’ve got an infographic about how the sinkhole formed, provided by the NCM with help by Jason Polk, Assistant Professor of Geography and Geology at Western Kentucky University.

Why did this happen? Here's why. Jason Polk, Assistant Professor of Geography & Geology at Western Kentucky University, says that water from storms and underground flowing over time (years to centuries) focused on the area under the Skydome, which is likely connected to other caves and sinkholes in the area. That water eroded away the rock, and washed away the soil into the voids below.
