California hiker dies in Death Valley, heatstroke suspected

DEATH VALLEY, Calif. (AP) - A San Francisco man died while hiking in Death Valley National Park, where temperatures can be among the hottest on Earth, authorities said Saturday. Lawrence Stanback, 60, died Wednesday while hiking near Red Cathedral along the Golden Canyon Trail, according to a joint statement from the park and the Inyo County Sheriff's Office. That day temperatures reached 108 degrees Fahrenheit (42 Celsius). Park rangers received a report of a suspected heatstroke Wednesday afternoon and set on foot to look for Stanback. He was already dead when the rangers found him, officials said.

The day I walk under the intense, scorching heat was 120 degrees. I barely died. Good thing I drank plenty of water, however I vomit water.
The heat cause my body to reject water.

The perfect time to roam around is when the sun almost set on the horizon.
