The objective of this observation is to examine a straight ridge that might be a dike. Sometimes magma (molten rock) below the surface may fill an existing fracture, even pushing the fracture open in the process. As the magma cools, it solidifies into a tabular rock mass, and that resulting cooled volcanic rock is called a dike.
