Three hikers died from apparent heat-related illnesses in the Grand Canyon over the past week. Temperatures in the inner canyon can exceed 109°F. The U.S. National Park Service urged hikers to avoid trails during peak heat hours.
Scientists are using advanced technology like mobile lidar to map the Grand Canyon's hidden cave and fracture systems, crucial for understanding its water supply. Research combines cave mapping with snow and climate data to assess how drought and climate change impact this vital groundwater network.
Grand Canyon National Park authorities are seeking public assistance in locating Sandarsh Krishna, a 26-year-old Indian man reported missing on April 28, 2026. He was last seen on the Rim Trail along Hermit Road between Bright Angel Lodge and Mohave Point between 4 pm on April 27 and 12 am on April 28, wearing athletic clothing. A black backpack believed to belong to Krishna was later turned in to hotel personnel at Bright Angel Lodge.
A new study published in Science supports the theory that an ancient lake overflow in the Bidahochi basin triggered the Colorado River to carve the Grand Canyon. Researchers analyzed zircon crystals in sandstone samples from both the Grand Canyon and the basin, finding chemical signatures that suggest a connection between the regions before the canyon fully formed. The theory proposes the lake reached a tipping point, spilling over elevated terrain like the Kaibab Arch and forcing water to carve a new route.
