Two people died while on outings in the Smokies area.
One man drowned at the base of Abrams Creek Falls in Great Smoky Mountains National Park; the other was killed when his motorcycle veered off Foothills Parkway into a drainage ditch, according to the National Park Service.
In Friday's incident, Stephen Musser, 73, of Roswell, Georgia, was pushed under while swimming beneath the falls at about 2:15 p.m. His body, which was entrapped in debris under the surface, was recovered about seven hours later by divers from the Blount Special Operations Rescue Team.
Park officials warned visitors about the risks involved in entering park waters, noting unexpectedly strong currents and sieve-like debris common in streams and rivers.
Sixty people have drowned within the national park over its 85-year history; 10 of those have perished near Abrams Falls, according to the park service.
Rangers also responded at about 11:35 a.m. Saturday to a fatal motorcycle crash on Foothills Parkway between Walland and Wears Valley.
Park officials said David Birdsong, 57, was heading south at mile marker 24 when he lost control of his motorcycle and left the roadway. He was pronounced dead while en route to a hospital.
Rangers said speed appeared to be a factor in the crash.
Birdsong was the fourth motorcyclist to die on the parkway or in the national park this year.
Car crashes account for 40 percent of fatalities along the parkway or in the national park. Twenty percent of those fatalities involve motorcycles, national park officials said.
