What Drained an Entire Lake Overnight With No Storm or Warning? Scientists Have an Answer

Lakes in glacial and karst regions are vanishing and refilling without rain, baffling observers. Scientists explain these phenomena through underground processes: hydrofracture in ice sheets and sinkholes in limestone landscapes. Meltwater and groundwater find hidden exits, traveling through subglacial channels or cave systems, then slowly return as underground reservoirs and blocked passages shift, revealing a dynamic hidden plumbing system.
