A teenage swimmer at Yosemite National Park was swept over 594-foot Nevada Fall on Saturday afternoon.
According to the park, Aleh Kalman, 19, of Sacramento, was swimming above Nevada Fall, approximately 150 feet from the precipice, according to witnesses, where he was swept away by the current. He was swimming back from a rock in the middle of the river when the current swept him downstream to the edge of the waterfall, witnesses told park rangers.
Kalman came to the park with a church group and was hiking the Mist Trail when the accident occurred, according to park officials.
Ground teams, along with a California Highway Patrol helicopter, were immediately dispatched to the location of the waterfall to begin searching for Kalman. Search efforts continued throughout the evening until fading light prevented further efforts.
On Saturday afternoon, the Merced River, which pours into Nevada Fall, was flowing at roughly 500 cubic feet per second (CFS), which represents a very swift and powerful spring flow of water. On Sunday morning, the river was flowing at approximately 650 CFS with water temperatures in the low 50s.
So here is a warning that is posted at river near were he was swimming:
Seems like a case of darwin at work.
