Recovering the dead in Texas and very possibly Louisiana is going to be difficult because of the length of time the bodies will be decomposing. There is also the issue of sediment and mud. If covered in mud they might be intact. At least their bones. But, there is no guarantee there will be recovery. List the missing and eliminate the possibility of deaths of citizens.

The land after 911 in Lower Manhattan was consecrated because of the diffuse nature of the crime. Given the religious nature of Texans local ministers, priests, imams and the like need to consider consecrating lands if the dead are irretrievable.
