Story summary

Brian Seibert, a 53-year-old experienced climber from California, died after falling from Mount Morgan North, a 13,000-foot peak in Mono County on Sunday, October 4. Rescuers found him dead at the base of Grand Central Couloir, a gully off the summit, three days later. Seibert had last sent a text around 7 p.m. that he was returning down the mountain after signing into the summit registry. After he didn't return home, friends reported his disappearance to authorities on Monday, leading Mono County Sheriff’s Office and other teams like YOSAR and Cal Guard to initiate a search involving scent-sniffing dogs, helicopters, including a CH-47 Chinook, and extensive cell phone data analysis. Despite the challenging terrain, rescuers identified an anomaly near the bottom of Grand Central Couloir on Tuesday morning and confirmed it was Seibert’s body. The rescue efforts took over 305 hours in total.
