It's time to start a new thread - this will cover the remaining work in Seitah and the drive back to the landing site.

From the CNN report: "The rover's latest finding suggests that the bedrock it has been driving over since landing was once formed by volcanic lava flows -- something that was "completely unexpected," according to mission scientists."
Prior to landing the The consensus seemed to be that the crater floor was flooded by lava some 300 million years after the lake dried up. This embayed sedimentary/deltaic deposits including the olivine rich Séítah unit. Perseverance's track south and along Artuby ridge skirted Séítah and she didn't cross onto the olivine rich unit until Sol 201. So traversing eroded lava deposits and seemingly some sedimentary deposits since landing would not seem particularly unexpected. |

Eh, the quality level of consumer journalism has dropped quite a bit - as noted by some reviews of the print version of Time Magazine 's "Person of the Year" edition getting basically ALL the basic rocketry facts about Elon Musk wrong. |
