Lots of vertical cracks, or dikes, in the rock set the geology of the wandering hill apart from others. The dikes filled with lava, funneling it through a zone of limestone saturated with water.

Profile Rock is a dike that radiates from the Spanish Peaks in Colorado. To see the world-class formations, the Geological Society of America has looked to Brian Penn for days-long trips around ...

Dikes in which two different liquids flowed simultaneously, usually called composite dikes, naturally fall into two classes depending on which lithology forms the contact with the country rock, and ...

But by blocking that water and pushing more freshwater deeper below ground, saltier water appears to have moved up to shallower areas outside the dike, according to the U.S. Geological Survey.
