Cross-Sections

Cross-sections show the relationship between geologic units in the subsurface and compliment the geological map. Follow the matching line across the map (e.g. A – A' toward the top of the map) and compare the cross-section at the bottom. This helps you relate what you see on the surface to what is going on underneath.
