According to a National Park Service news release, the 42-year-old Belgian tourist was taking a short walk Saturday in the Mesquite Flat Sand Dunes in 123-degree heat when he either broke or lost his flip-flops, putting his feet into direct contact with the desert ground. The result: third-degree burns.
“The skin was melted off his foot,” said Death Valley National Park Service Ranger Gia Ponce. “The ground can be much hotter — 170, 180 [degrees]. Sometimes up into the 200 range.”
Unable to get out on his own and in extreme pain, the man and his family recruited other park visitors to help; together, the group carried him to the sand dunes parking lot, where park rangers assessed his injuries.
Though they wanted a helicopter to fly him out, helicopters can’t generate enough lift to fly in the heat-thinned air over the hottest parts of Death Valley, officials said. So park rangers summoned an ambulance that took him to higher ground, where it was a cooler 109 degrees and he could then be flown out.
And for those of you who only know temperatures based on brewing tea or coffee:
123F: Probably insufficient for even fairly delicate teas. You could probably make “sun tea” at this temperature by leaving tea in room temperature water to be heated by the sun, but this is not recommended as anything below ~130F is considered the danger zone for bacterial growth.
170F: This is the appropriate temperature for delicate or green teas to preserve flavor, antioxidants, and prevent bitterness.
200F: An acceptable temperature below boiling (212F) for black teas and coffee where overextraction is minimal.
109F: Unacceptable for tea brewing, barely above body temperature.
We make sun tea by leaving it outside (90’s, 35c). In the sun. It’s a bit like cold brew, it takes longer to extract the flavors.
It’s also bitter so generally sweetened with lemon juice. And some form of sugar. (Honey preferred.)
Correct, I should clarify, you are likely safe brewing sun tea at those ambient temperatures because the glass of the brewing vessel will trap the sun and heat the tea higher than that, like a car traps heat on a hot day. You’ll likely hit 130F+ easily and be out of the danger zone!
