Morehave been found at drought-stricken National Recreation Area east of Las Vegas, authorities said Sunday.
It's the fourth time since May that remains have been uncovered as Western drought forces the shoreline to retreat at the shrinking Colorado River reservoir behind the Hoover Dam.
National Park Service officials said rangers were called to the reservoir between Nevada and Arizona around 11 a.m. Saturday after skeletal remains were discovered at Swim Beach.

Adating back to World War II has also been revealed from underneath the shallow waters.
The lake surface has dropped more than 170 feet since the reservoir was full in 1983.
Last week, the United Nations issued a warning that the water levels in Lake Mead and Lake Powell are at their lowest ever and are getting perilously close to reaching "dead pool status." Such a status means that the water levels are so low that water can't flow downstream to power hydroelectric stations.
Last month, satellite images released by NASA showeddramatic changes between 2000 and 2022, as its water level has reached its lowest point in more than 85 years.
The drop in the lake level comes while a vast majority of peer-reviewed science says the world is warming, mainly because of rising levels of carbon dioxide and other greenhouse gases in the atmosphere.
Scientists say the U.S. West, including the Colorado River basin, has become warmer and drier in the past 30 years.
