A 69-year-old man died and another man and four Boy Scouts were rescued after they all suffered from heat-related illnesses in a hiking area near the Nevada-Arizona line, authorities said.
Lake Mead National Recreation Area park rangers and other agencies carried out searches Saturday afternoon as temperatures hit 110 degrees, and after receiving calls for help from the men and the Scouts in Arizona's White Rock Canyon area, about eight miles from Boulder City.
A news release stated Clawson Bowman Jr. of Las Vegas was located about a mile from the trailhead, but was pronounced dead. Rescuers aided the other man until an air ambulance arrived.
The Boy Scouts were reported lost, but they maintained phone links until they were rescued by an air crew and brought to the trailhead, where they were treated by paramedics.
An autopsy will determine the cause of Bowman's death.
Closer to home, Phoenix fire officials said crews responded to 20 heat-related calls during a 24-hour period from Friday at 8 a.m. ending Saturday at 8 a.m.
The high in Phoenix on Saturday hit 110 degrees at 4:11 p.m. The normal for this time of year is 102 degrees.
Highs will continue to run a good 5 to 8 degrees above normal through the upcoming week. Although it might not be record heat, it's going to be very hot any way you slice it.
There are no weather features to change this pattern. Some forecast models hint that by next weekend, the Valley might shave off a few degrees, however moisture could creep up a bit making it feel equally as warm.
