Lunar mountains and wrinkle ridges
Cool image time! The photo above, taken by Lunar Reconnaissance Orbiter (LRO), was released today by the orbiter’s science team, and provides us an oblique look at the mountains dubbed Montes Recti (lower right) and the wrinkle ridges near them (lower left). The highest point in this mountain range is about 5,900 feet high.
The image looks west across the northern part of the mare region dubbed Mare Imbrium, the dark area on the Moon’s visible hemisphere near its top. In the distance can be the mountains that form part of mare’s rim. The rounded peak in the top right is Promontorium Laplace (about 8,530 feet high). It is named this because it projects out (a promontory) into the mare a considerable distance from the rim. The crater at top center is Laplace D. As for the wrinkle ridges, the scientists describe them like so:
Tectonic landforms are those formed by forces that act to either contract or pull apart crustal materials. These forces develop faults or breaks in the crustal materials, and movement or slip along the faults form either positive or negative relief landforms. On the Moon, positive relief contractional landforms are the most common. The most significant contractional landforms on the Moon are wrinkle ridges, found exclusively in the dark mare basalts.
Essentially, something caused the ground to contract, which caused it to break at these ridges and be forced upward.
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.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

Typo alert: 1st paragraph: “mountain change” should be “mountain range”.
Michael McNeil: Thank you. Typo fixed.
My first thought was Aldrin’s opine: “Magnificent desolation”.
