Yosemite National Park, a major U.S. tourist destination known for its stunning granite cliffs, is facing safety concerns due to newly discovered cracks in its rock faces. More than 1,000 incidents of rockfall have been reported in the park, but a recent crack, identified by climbers in August 2023, is currently posing significant risks, leading to trail and climbing area closures. Named “Supernatural,” this crack has widened from one inch to four inches since its discovery.
Park officials, including climbers and geologists, are actively monitoring the situation, noting unusual sounds and rock movements. The closures encompass popular climbing routes like Serenity Crack and Super Slide as a precaution against potential rockfalls.
Rockfalls are a natural geological process, but human activities can exacerbate risks. Researchers and the U.S. Geological Survey are using advanced technologies to study these hazards, aiming to improve safety measures. Despite these challenges, there are concerns about visitor safety during government shutdowns, which can lead to dangerous behaviors and unmonitored conditions in the park, further complicating rockfall risks.
