The History Guy – Dandelions and Civilization
A evening pause: Some forgotten history worth learning. Might even make you want to try the plant in your next salad.

A collapsed Martian crater in a glacier?

Today’s cool image to the right, cropped and reduced to post here, is another example of evidence that the mid-latitudes of Mars are covered with glaciers and ice. The photo, taken on April 25, 2020 by the high resolution camera on Mars Reconnaissance Orbiter (MRO), shows many of the squashed and blobby features found in these mid-latitudes.
What makes the image even more interesting is the small crater in the center of the larger crater. The floor of that larger crater seems filled with glacial fill, and it appears that when that smaller impact occurred it caused the nearby surrounding fill to collapse downward, producing the oblong off-center depression. At least that’s my uneducated guess, which I admit could easily be wrong.
Even if my hypothesis is wrong, the visual evidence here supports the theory that this region, dubbed Deuteronilus Mensae, has lots of buried ice glaciers. Consider for example the distorted crater to the southwest of the big crater. It sure looks like at some point it was heated suddenly, maybe by the impact of the main crater, so that its rim was warped and reshaped, in the manner that ice would be warped and reshaped by sudden heat. Moreover, all the craters in full image appear to have glacial fill.
The overview map below adds weight to this conclusion.

COVID-19 is simply not life-threatening
The fading and not very threatening COVID-19 epidemic
in California. Note how masks appear to increase the
disease’s spread. Note also how this doesn’t seem to
change the death toll significantly. Go here for more details.
In the past few days there have been a flurry of new reports proving once again that the panic over the Wuhan virus was completely unnecessary, that the disease was exactly what the initial data suggested, a variation on the flu that would be, like the flu, harmless to the healthy and young while dangerous to the elderly sick.
And like the flu, the Wuhan virus required no extreme measures. All we had to do was protect those elderly sick, and let everyone else continue living their lives normally.
First we have the revelation this weekend, from the CDC no less, that the number of people who died only from COVID-19, with no other health issues, was only about 6% of the total deaths assigned to the disease, or only about 9,700 people total, an infinitesimal percentage of the total population.
The Centers for Disease Control and Prevention (CDC) website disclosed the shockingly small number of people who died from only the Wuhan coronavirus, with no other cause of death mentioned. Hold on to your hat because here it is: out of the 161,392 deaths in the CDC data, just six percent, about 9,700 deaths, were attributed to the coronavirus alone. According to the CDC, the other 94 percent had an average of 2.6 additional conditions or causes of deaths, such as heart disease, diabetes, and sepsis. [emphasis mine]
Let that sink in. The Wuhan virus killed you only if you had an average of slightly less than three serious chronic health conditions. And generally you had to be elderly, with the average age of death 78 years old. Otherwise, just like the flu you might have been sick for a few days, but you would have recovered and been able to go on with your life as normal. This data once again demonstrates that the masks, the shut downs, and the economic disaster were all unnecessary.
Then on Friday we had another research paper, one of a long continuing string of papers, finding once again that COVID-19 is of no threat to young children at all, that they not only don’t get sick from it they also don’t infect anyone else.
