Rangers with the National Park Service once again received a report of human skeletal remains discovered in the Lake Mead National Recreation Area.
Two sisters from Henderson were paddle boarding on the drought-stricken Colorado River reservoir when they spotted bones Saturday in the Callville Bay area, the Associated Press reported.
Lindsey Melvin told KLAS-TV that they thought it was a bighorn sheep. But when they noticed a human jaw, the women called park rangers.
The National Park Service confirmed in a press release the bones are human.
The Clark County Coroner's Office is investigating the cause of death and no further information has been released. Police are not treating the find as a homicide.
The find comes just days after a body was found in a barrel that was revealed at Lake Mead due to shrinking water levels.
Investigators believe that victim was shot and killed in the mid-1970s to early 1980s.
Drought has dropped the Lake Mead water level so much that Las Vegas’ uppermost water intake became visible two weeks ago.
Police have speculated that receding water lines could lead to more bodies being discovered.
