These are usually ofter, younger, and unconsolidated rocks. These workers could then secure the bridge's towers directly to the bedrock. Soil color is often tied to a number of soil properties, such as organic matter, which make the soil dark in color, or iron oxides, which impart a rusty-reddish hue to the soil. I am trying to determine the DTB (I just learned about Depth to Bedrock and I was so happy to learn a new phrase!) Whatever the case, there is "a huge trend of sinking throughout Louisiana, making it the hotspot of the country in terms of this kind of phenomenon," said geologist Stephen Leatherman of Florida International University.
