Probably only just under freezing at home, 28 to 30 degrees F. I'm in California. One Summer, 117 F in the Suburbs. That same day it was 113 in DT LA and a mere 112 in Death Valley! Death Valley can exceed 120 often.

At my age I was astounded to have never found out before that wind chill does not lower the temperature it just makes it feel colder. I’d always wondered how car makers fitted outside temperature gauges to cope with this, but of course they don’t have too. If you drive your car in a set ambiant temperature, it doesn’t matter how fast you drive, the reading remains the same. Only road heat whilst stationary might screw things a bit.
Wind chill though is important when it comes to survival. Although the given temperature might, for instance, be -10c your warm clothing will be far more effective at keeping you warm when there is no wind than it would be if a strong wind is driving the ambient temperature through your clothing.

The air flow causes the heat to be removed from the surface, causing more heat 'to move' to where the heat was removed from... in simple terms.

It might not be Wordsworth, Keats or Lord Byron, but I like it. And it sounds like a reasonable request.

If you are not able to lay your hands on your copy right away, below the biographical statement about him in this site, most, if not all of Robert Service's works are available.
Not the same as holding a book, but a way to look back through his writings, anyway.

John Matthews Loc: Wasilla, Alaska

Don’t know how cold because the thermometer did not read below -50F as we traveled up the Yukon in Alaska towards Nome via dogsled.
My camera did not work either. February 2007. Not fun camping but interesting. Each day was glorious sunshine, no animal life or tracks to be seen.

True.
The convective heat loss of our bodies is increased in the deep cold by the blowing effects of the wind. Something like the reasons why internal combustion engines, refrigeration units, air conditioning systems, etc use designed airflow for cooling purposes....even if liquid cooling is also a part of the cooling system. The airflow is still utilized to convect heat away from the engine/cooling systems components.
Clothing designs can help slow that convective loss from our bodies, but I don't think researchers have found a way to make affordable clothing that can totally prevent that increased heat loss and still allow the wearer to have useful mobility.

Windchill factor charts are not absolute values, and have been revised a few times through the years since first being "invented" by a couple of Antarctic researchers/scientists.

Evaporative heat loss is a part of our loss of body heat, also.
Seems Australian researchers try to evaluate and enumerate that to include effects of humidity in their deep cold research measurements and chill factor tables.
North American researchers don't seem to have given the evaporative cooling effects much attention and inclusion in their testing.
If memory serves correctly, UK (or maybe it was Scandinavian) researchers have included evaporative heat loss in some of their researches, but not close to the extent the Aussies have.

(Are congratulations in order if you read through to the end of this, unlike the commenters in UHH who write they won't read a comment if it is more than a couple sentences, or 50 words or whatever? 🤔. )

I've done some brief looking here, and haven't yet located again some of the accounts of the fellow who froze to death in Death Valley during the hot season.
He had an invention of a self-contained personal cooling system that would enable explorers, prospectors, adventurers, whoever, to go traipsing out into Death Valley in the hot months. (Ok, it may have been somewhere in the Mojave Desert, but if I recall correctly, it was a Death Valley incident.)

When he did not return in a reasonable number of hours, after having told an acquaintance he was going into the Valley to put his invention through its "maiden voyage", an attempt was made to go find him.
He was found in the heat, dead on the ground, with ice still present in his nostrils and airway.
Something about, his self-contained cooling system was a backpack of dry ice with a way to provide cooling to his torso and provision to cool intake air he breathed. Seems he succumbed to the ice that built up internally.

I experienced -40 deg F at old faithful...Yellowstone in winter, and yes, it is quiet & peaceful.

When I was in the Navy, I was sent for training to (then) Camp Drum in (way) Upstate New York for "cold weatrher training." I was a corpsman and attached to a Marine unit. Also, I had recently recived orders that I would be transfering to a ship out of Norfolk, VA. Couldn't convince the Chief over me to send a different person to the training. Anywho, I went. One of the training exercises was two days in the field with an overnight stay. We spent the night in tents with the wind chill at 63 below. The tents did little if anything to protect aginst the cold, other than to diminish the wind slightly. Fortunately we had only a couple cases of minor frost bite and no extremities lost.

In northern Maine on a base it was down to -80f with chill of -100f and the wind was constant at night never want to return
