The divide in a giant Martian lava river
Click for original image.
Cool image time! The photo to the right, rotated, cropped, reduced, sharpened, and annotated to post here, was taken on September 24, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
As indicated by the arrows, this is a frozen river of lava on Mars, flowing to the southwest and then splitting into two streams, one to the west and the other to the south. Being a Martian lava flow, when it was liquid it flowed much faster than lava on Earth, almost like a thick water. The flow bored into any high features, such as the two mesas in this picture, and streamlined their shapes, tearing material away as the lava moved by quickly. In the process the lava flow exposed many layers in those mesas, indicating many other previous lava flow events.
The crater in the lower mesa, where the stream splits, appears to have been more resistent to the flow, having been compacted into harder and denser material by the impact itself.
The white dot in the overview map to the right marks the location, with the rectangle in the inset indicating the area covered by the picture above. The inset also shows a wider view of the two diverging lava streams.
This particular Martian volcanic event is part of the Athabasca flood event, believed to be the youngest major volcanic event on Mars, taking place only about 600 million years ago and covering an area about the size of Great Britain in only a matter of weeks. This particular spot, where the flow split, is very near the vent that released the entire eruption, only about 90 miles away to the northeast. Thus, the lava river here was very large and distinct, with frozen features suggesting it was moving very fast and deep.
From this spot however this river of lava divided, with about two thirds flowing to the west to coat a vast region, while the remain one third headed south. The blue shaded areas on the overview map show roughly the territory both flows inundated.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
