Glaciated areas with weathered bedrock can typically vary one foot to the next. The heavy clay soils, referred to as vertisols, are highly fertile. This landscape offers geologists a clue about how far glaciers extended during the Ice Age. The bedrock topography is shown as 50-foot (15-meter) contours of bedrock elevation above mean sea level (msl). It is very difficult to dig through this layer. Soil pH indicates relative acidity or alkalinity. The midcontinent crust is presumably sinking very slowly toward the Gulf Coast region of Texas and Louisiana. The settling has been going on for ages, but the surface really began dropping fast during the 20th century because of man's doing: The levees built to keep the Mississippi within its banks all but stopped the floods that used to lay down new layers of soil over the land.

Some house levelers use a technique called "mudjacking" drilling holes in the foundation, then pumping in a mixture of mud and cement under pressure to raise and level part of a building. Unlike the horizon above, this horizon does not comprise rocks or boulders, but instead is made of continuous mass of bedrock. The bedrock of the southern part of the state experienced less weathering and erosion, and was left with less glacial till as the glaciers retreated. Alluvium indicates a soil that has been deposited by rivers. Not far from Leres' home, an auto dealership won $3.7 million in 1999 in a lawsuit against the Orleans Parish Sewerage & Water Board over damage from a drainage project.

Bedrock can extend hundreds of meters below the surface of the Earth, toward the base of Earth's crust. Aquifers, underground pockets of water, exist in porous bedrock formations, such as sandstone. Bedrock is made up of igneous, sedimentary, or metamorphic rock, and it often serves as the parent material (the source of rock and mineral fragments) for regolith and soil.

Water from wells drilled into bedrock may contain dissolved iron, manganese, calcium, or other undesirable constituents that occur naturally in higher concentrations in some rocks than in others. The measured displacements are a combination of movement of the ground and of individual structures. The term " bedrock geology" describes the study of the rocks at and below the bedrock surface. A bedrock map is the geologist's prediction of what kind of rock will be encountered below the surface based on observed surface exposures.
