Three outlets report that Brian Seibert, 53, died after a fall while climbing Mount Morgan, a peak of about 13,000 feet in California’s Sierra Nevada. According to the Mono County Search and Rescue Team, which the outlets cite, Seibert sent a text around 7 p.m. on Sunday, October 4, saying he was heading down. He was reported missing on Monday, October 5, after he did not return as expected. Rescuers spotted an anomaly from the air in a steep gully and recovered his body early Wednesday, more than 72 hours after the fall. The Daily Mail gives the summit height as 13,754 feet.
