About This Lesson
Karst topography means a landscape that has underlying limestone as its bedrock where caves, sinkholes, underground rivers, and springs can form. You’ve heard of Mammoth Cave, right? Well, that national park and thousands of other limestone caves around the country we formed because they were located in karst topography. These karst areas also often have direct pathways from the surface down into groundwater aquifers because of how easily water passes through dissolved cracks and channels in the limestone. And why does water pass so easily through this limestone?
