Mapping the Grand Canyon's Hidden Waterways

Scientists are mapping the Grand Canyon’s hidden underground cave systems to protect its vital springs—the only water source for millions of visitors and the entire ecosystem. Using advanced lidar, they’ve charted over ten kilometers of subterranean passages, revealing how snowmelt travels through fractured rock. This “Swiss cheese” karst network moves water rapidly, making it vulnerable to contamination from wildfires or bacteria, which could force park closures. Next, they’ll combine satellite and airborne lidar data to link surface features with underground flow, especially as snowpack declines. The research has global implications, helping manage karst water systems for billions worldwide—and supporting local Native American communities.
