Slightly off topic, but since you mentioned deserts, I noted that one of the most extreme places in USA - Death Valley California, had flash floods last week. https://www.iflscience.com/environment/a-giant-lake-has-appeared-in-the-middle-of-death-valley/

The article says Death Valley National Park holds the record for the hottest air temperature ever recorded on Earth 56.7C (134F) which occurred on July 10, 1913, at the aptly named Furnace Creek. It also holds the record for hottest ground temperature, a sizzling 93.9C (201F) on July 15, 1972, and the record for hottest month ever recorded with an average day and night temperature of 42.3C (108.1F) for July 2018 (which broke its own record set the previous July). It has a yearly average rainfall of 6 centimeters (2.36 inches) a year, making it one of the driest places on Earth too.

Visiting Furnace Creek will be on my bucket list if I ever feel the need to make one. Australia's heat records make us look like pikers. Although we still got the record for number of consec days 100 or over at Marble Bar. So that is something

A mild 44C on the day I visited there. I just love geography, geology, weather and climate so loved the whole area. rest of Family ( 2 teenage girls) unimpressed.

I confess to not being a heat lover. At least not humid weather (who is). But I am fascinated by Earth extremes like many are. In late Nov I am taking a trip to the Holy Land. The Dead Sea is on my intinerary as well as a town called Beit She'an in the Jordan Valley south of sea of Galilee. Interestingly enough there is a place not far from Beit She'an called Tirat Zvi which has recorded a recognised 54 in 1942. The Jordan Valley, like death Valley is below sea level. Crazy hot spots

I did get to Death Valley for a brief visit around 13 years ago, and it was a mild 41 deg C. It was still an extreme for me though because the day before we were in Yosemite national park and we had snow there.

I think that is around 250km distance between the two places. Incredible contrast. I wonder what the world record would be for hottest temp and coldest temp 250km from each other.

In a straight line Mount Whitney at 4419m (14,500ft)is not that far from Death Valley. Closer to Death Valle Telescope peak is 3000 odd metres.

We stayed at Bishop in a valley between ranges NE of Death Valley, so rain shadowed in every diraction. I think the place is dryer than most parts of inland Australia, yet is popualr for trout fishing

Certainly dry in the rain shadow of such high peaks. According to wikipedia, the lowest point in north America, Badwater Basin, averages 48mm per annum of rainfall. The evavporation rate is an 3800mm per annum and hence "This is the greatest evaporation potential in the United States, meaning that a 12 ft (3.8 m) lake could dry up in a single year." The Dead Sea by contrast has an evaporation rate of up to 1600mm per annum, whilst Lake Eyre can be up to 2000mm with a lot of water in it.
