A hiking trip meant to celebrate a long-held dream ended in tragedy when a 20-year-old Arizona State University student died after falling hundreds of feet while descending Yosemite National Park’s famous Half Dome. Grace Rohloff, an experienced hiker known by friends and family for her adventurous spirit, had spent years hoping to climb the iconic granite summit. When she finally secured the highly sought-after permits required for the challenging hike, she invited her father, Jonathan Rohloff, to join her for what was meant to be an unforgettable father-daughter adventure.

On July 13, 2024, the pair began the demanding journey up Half Dome, one of Yosemite’s most well-known and physically challenging hikes. The full round-trip route stretches roughly 16 miles and includes steep elevation gain before reaching the final section where hikers climb the dome’s granite face using steel cables anchored into the rock. For many outdoor enthusiasts, reaching the summit represents a major accomplishment, and Grace had been determined to experience the climb.

By the time they reached the top of Half Dome, the effort had paid off. Standing above Yosemite Valley, the two shared a moment of celebration after completing the difficult ascent. According to accounts from her family, Grace hugged her father, told him she loved him, and took in the sweeping views from the summit. The moment was captured in a photograph that would later become the last image taken of the pair together. In the picture, they stand smiling against the dramatic granite landscape, proud of the milestone they had just achieved.

After spending time at the summit, the pair began the descent down the steep cable section used by hikers to navigate the dome’s exposed granite slope. At that point, conditions began to change rapidly. A thunderstorm moved into the area, bringing heavy rain that quickly soaked the granite surface. The smooth rock face of Half Dome can become extremely slippery during wet conditions, creating dangerous footing even for experienced hikers.

As they continued descending, the rain intensified. According to reports of the incident, Grace had made it about three-quarters of the way down the cable section when she lost her footing on the wet rock. In a matter of seconds, she slipped and began falling down the steep mountainside. Despite her father’s attempts to reach her, the terrain and suddenness of the accident made it impossible to stop the fall.

Grace tumbled an estimated 200 to 250 feet down the slope. Authorities later determined that she suffered a fatal head injury during the fall and likely died instantly. The accident left her father witnessing the devastating moment as the joyful climb they had shared earlier that day turned into a heartbreaking loss.

The tragedy has drawn attention to the potential dangers of the Half Dome cable route, particularly during storms or wet weather. The cable system allows hikers to grip metal supports while climbing the steep granite incline, but when the rock becomes slick, maintaining footing can become extremely difficult. Park officials have long warned hikers to avoid the cables during storms or when lightning and heavy rain move into the area.

Following the accident, Jonathan Rohloff has spoken publicly about the risks associated with the cables during sudden weather changes. While the Half Dome hike remains one of the most popular routes in Yosemite National Park, he hopes greater awareness and safety measures could help prevent similar tragedies in the future. His advocacy has focused on encouraging hikers to pay close attention to weather forecasts and to exercise caution if conditions change quickly while on the mountain.

Friends and family remember Grace Rohloff as someone who embraced life with enthusiasm and kindness. Those who knew her say she had a natural ability to make people around her feel valued and included. Her love for adventure, travel, and the outdoors was a defining part of her personality, and climbing Half Dome had been one of the experiences she most hoped to accomplish.

While the events of that day ended in unimaginable loss, those closest to Grace say her spirit continues to live on through the memories she created with the people she loved. For her father and family, the final photograph taken at the summit serves as a reminder of the joy and pride she felt in achieving her goal — a moment that reflected the fearless and vibrant way she approached life.
