PSP_20_008753_1876_XN_07N211W.jpgPyramid?174 visiteSu immagini come questa potremmo speculare per anni, senza arrivare a nulla (come ci insegna la - ormai - "antica" vicenda di Cydonia Mensae). Dunque la proponiamo così com'é (dettaglio magnificato di un frame MRO).
Interessante.... O no?!?MareKromium

Dust_Storm-MGS-41669_Zurek-1-PIA22519.gifThe Global Dust Storm that wiped Oppy away (Annotated)119 visiteCaption NASA:"This set of images from NASA’s Mars Reconnaissance Orbiter (MRO) shows a fierce, giant Dust Storm is kicking up on Mars, with Rovers on the Surface indicated as icons. The spread of the Storm can be seen in the salmon-colored overlay. These images from MRO's Mars Color Imager start from May 31, when the Dust Event was first detected, and go through June 11, 2018.
MRO creates Global Maps of Mars but roll maneuvers for targeted observations produce gaps in the coverage, which appear as black gores in the aforementioned Maps. On some days there are data drops where partial or full orbits of coverage are missing. Green and purple observed in the South Polar Region indicate saturated pixels. Latitude is indicated along the Vertical Axis. Longitude is indicated along the Horizontal Axis".MareKromium

PSP_004277_1530_RED-PCF-LXTT-01.jpgFeatures of Holden Crater's Rim (CTX Frame "B" - Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)78 visiteHiRISE image PSP_004277_1530 covers a portion of the rim of Holden Crater, revealing breaches created when water over-topped the Rim and incised a series of Channels as it flowed down the Crater Wall.
The water responsible for the Channels was impounded outside of the rim of Holden in Uzboi Vallis (Holden Crater itself is approx. 150 Km in diameter).
Uzboi Vallis was interrupted when Holden Crater formed and the Rim formed an effective, temporary damn to flow farther to the North. Once the Uzboi Basin filled, water began flowing into Holden again, creating a series of low fan-shaped Deltas, alluvial deposits and a shallow, but relatively short-lived lake.
The Channels in this image were only active for a short time, as a Channel just to the East cut quickly into the Rim and became responsible for most of the drainage into the Crater.
The fact that most of the fan-shaped Deltas radiate from the Dominant Channel to the East rather than those in this image supports this scenario. MareKromium
