Second Tourist This Week Dies In Grand Canyon National Park
Authorities say a man from Germany is dead after a kayaking accident at Grand Canyon National Park.
Park officials say 43-year-old Hans Uhl was part of a commercial river trip. The group had just started its multi-day trip on the Colorado River on Wednesday when park officials received a call around 2 p.m. about an unconscious kayaker at Badger Rapids. Authorities say Uhl's kayak capsized and he was unable to right himself.
A safety boat was able to reach the kayak, but authorities say Uhl lost consciousness and couldn't be resuscitated. An investigation is being conducted by the National Park Service and the Coconino County medical examiner.
Uhl is the second German tourist to die in the park this week. Authorities say medics were unable to revive 64-year-old Wolfgang Hans-Joachim Glode on Monday night after he was reported to be unconscious. Glode was vacationing with his wife from Sievershagen, Germany.
