20-year-old Grace Rohloff fell to her death on Yosemite's Half Dome trail during a slippery descent in a rainstorm.

20-year-old Grace Rohloff, an Arizona State University student and experienced hiker, tragically fell to her death on Yosemite's Half Dome trail during a descent with her father, Jonathan Rohloff, on July 13. The hike began with clear skies, but a sudden rainstorm turned the descent's 400-foot cable section dangerously slippery. Grace lost her balance, slipped, and fell an estimated 200-300 feet, most likely hitting her head on the rock.
