Mountains of corpses at the bottom of a dry lake in the USA

More human remains have been found at Lake Mead less than
a week after authorities discovered the remains of a man in a
barrel amid a drought that has dropped the reservoir's water
level to historic lows.
A witness saw human skeletal remains in the Callville Bay area
of Lake Mead around 2:00 p.m. on Saturday, the National Park
Service said. The Clark County Medical Examiner has not yet
identified the cause of death.
Authorities said the investigation is ongoing

Police warned last week that more bodies could turn up in the
country's largest reservoir - located on the border of Arizona and
Nevada - after human remains were found in a barrel last Sunday.
National Park Service rangers found the barrel with skeletal
remains in an area near Hemenway Harbor on May 1 after boaters
spotted it (https://yhoo.it/3Pd1KUi).
The man was found shot and had likely been killed sometime
between the mid-1970s and early 1980s based on the type of shoes
the victim was found wearing, said homicide Lt. Ray Spencer, the
Las Vegas Review-Journal reported.
The bodies have become uncovered as Lake Mead's water level
dropped to 1,055 feet, the lowest since 1937, a year after Hoover
Dam created the reservoir.
Lake Mead and Lake Powell are the largest human-made reservoirs
in the United States, diverting water from the Colorado River to
40 million people in seven states, tribal nations, and Mexico.
Both lakes were full in 2000, but they now are roughly 30% full.
