The destruction of Gilchrist (Jeff Masters)

[Dead_Parrot]

Many of you have probably seen the photo of Gilchrist, Texas showing complete destruction of the town of 750 people, save for one lone home. High-resolution satellite imagery made available by NOAA's National Geodetic Survey (Figure 1) confirm that of the approximately 1000 structures existing in the town before Hurricane Ike, only about five survived the hurricane. Approximately 200 of these buildings were homes, and it is thought that some of the residents attempted to ride out the storm in their homes. According to media reports, about 34 survivors from Gilchrist and the neighboring communities of Crystal Beach and Port Bolivar have been fished out of Galveston Bay in the past few days. Rescuers who have reached Gilchrist have not been able to find any victims in the debris because there is no debris. Ike's storm surge knocked 99.5% of the 1,000 buildings in Gilchrist off their foundations and either demolished them or washed them miles inland into the swamplands behind Gilchrist. Until search teams can locate the debris of what was once was Gilchrist, we will not know the fate of those who may have stayed behind to ride out the storm.





Why did Gilchrist get destroyed?
It's rare to see a town so completely destroyed by a hurricane, to the point where you can't even see the wreckage. The neighboring towns of Crystal Beach, to the south, and High Island, to the north, were also mostly destroyed, but weren't swept clean of nearly all structures and wreckage. This is because Gilchrist was built in an unusually vulnerable place. It's bad enough to situate your town on a low-lying peninsula, as was the case for Crystal Beach. But in Gilchrist's case, the town was located at the narrowest point of the Bolivar Peninsula, at a point where it was only a few hundred meters wide (Figure 2). Not only did Gilchrist suffer a head-on assault by Ike's direct storm surge of 14+ feet, topped by 20' high battering waves, the town also suffered a reverse surge once the hurricane had passed. As Ike moved to the north, the counter-clockwise flow of wind around the storm pushed Galveston Bay's waters back across the town of Gilchrist from northwest to southeast. This second surge of water likely finished off anything the main storm surge had left.
