Soil Temperature Maps by Depth - National Weather Service Bedrock maps show what kinds of rock are beneath a given area, and how the different rocks are related to each other. Layers of impermeable material are both above and below the aquifer, causing it to be under pressure so that when the aquifer is penetrated by a well, the water will rise above the top of the aquifer. Whereas parts of southern Arizona or Louisiana may have thousands of feet of unconsolidated surficial material overlying bedrock, the "depth to bedrock" in Maine is generally only a few tens of feet and rarely over a hundred. Units of consolidated (solid) rock that underlie soils or other unconsolidated materials. 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.
