Karst is a geomorphological topic focused on landscapes developed predominantly in soluble rocks, such as limestone, dolomite, and gypsum, through dissolution processes. It encompasses the study of characteristic landforms and hydrologic systems including sinkholes, caves, blind valleys, disappearing streams, and underground drainage networks. Research in karst examines chemical weathering reactions (primarily carbonate dissolution by slightly acidic water), mass transfer in the critical zone, conduit versus diffuse groundwater flow, and vulnerabilities to contamination due to rapid infiltration. Karst studies integrate hydrogeology, geochemistry, and structural geology to understand aquifer behavior, solute transport, and the evolution of subsurface and surface morphologies.
Every year at Grand Canyon National Park, millions of visitors from all over the world stop at one of a dozen water spigots. Most people are on a rim, seeing the canyon's majesty for the first time, when they step off the ...

You trust the road beneath your tires. But what if that trust is misplaced? Sinkholes are increasingly turning ordinary streets into danger zones. And the cost of ignoring them is skyrocketing.
