Yes, I think it's common in the interiors of rocky planets in general. I understand the stuff on the moon is associated with places material from the mantle will be brought to the surface - igneous rocks and impact craters. But it's been quite a few years since I did any planetary geology.
This is one of the photos that look really interesting to me - probably something sedimentary given the layering:
Layering on hills on Mars is not unusual. This is an image by Curiosity of the hills surrounding Gale Crater - This is one of the photos that look really interesting to me - probably something sedimentary given the layering:

Incredible photo, never seen that before!It’s like someone took an DSLR photo in Utah. Absolutely fascinating to think it’s out on another planet with completely different atmosphere. What I’d give to stand and experience looking at it.

The scenery around Gale is pretty spectacular. Where Perseverance has landed doesn't look quite as dramatic - although scientifically it is interesting in its own right.It’s like someone took an DSLR photo in Utah.

I do wonder how long it'll be. They need to roll away from ingenuity, and ingenuity is supposed to fly within 30 days of launch, so it can't be long on that schedule.

You clearly haven't been to Utah.
You’re right! Im guessing I got confused and Utah is very flat? Haha oops. I think I meant Grand Canyon kind of area, my mistake.
Utah (the place) has scenery exactly like that, but it has an atmosphere consisting of 95% CO2 at 0.6atm. :P
Utah has great scenery. Monument valley, seen in a thousand spaghetti westerns, is in Utah.

Most Spaghetti Westerns filmed between 1964 and 1978 were made on low budgets and shot at Cinecittà studios and various locations around southern Italy and Spain.[11] Many of the stories take place in the dry landscapes of the American Southwest and Northern Mexico, hence common filming locations were the Tabernas Desert and the Cabo de Gata-Níjar Natural Park, an area of volcanic origin known for its wide sandy beaches, both of which are in the Province of Almería in southeastern Spain. Some sets and studios built for Spaghetti Westerns survive as theme parks, Texas Hollywood, Mini Hollywood, and Western Leone, and continue to be used as film sets.[12] Other filming locations used were in central and southern Italy, such as the parks of Valle del Treja (between Rome and Viterbo), the area of Camposecco (next to Camerata Nuova, characterized by a karst topography), the hills around Castelluccio, the area around the Gran Sasso mountain, and the Tivoli's quarries and Sardinia. God's Gun was filmed in Israel.

Next steps, some sort of tentative movement or tell it where to go and off it trundles?Greshamst said:

Just make it £5 a can now to start saving up the money.

NASA’s Mars 2020 Perseverance rover performed its first drive on Mars March 4, covering 21.3 feet (6.5 meters) across the Martian landscape. The drive served as a mobility test that marks just one of many milestones as team members check out and calibrate every system, subsystem, and instrument on Perseverance. Once the rover begins pursuing its science goals, regular commutes extending 656 feet (200 meters) or more are expected.
“When it comes to wheeled vehicles on other planets, there are few first-time events that measure up in significance to that of the first drive,” said Anais Zarifian, Mars 2020 Perseverance rover mobility test bed engineer at NASA’s Jet Propulsion Laboratory in Southern California. “This was our first chance to ‘kick the tires’ and take Perseverance out for a spin. The rover’s six-wheel drive responded superbly. We are now confident our drive system is good to go, capable of taking us wherever the science leads us over the next two years.”
The drive, which lasted about 33 minutes, propelled the rover forward 13 feet (4 meters), where it then turned in place 150 degrees to the left and backed up 8 feet (2.5 meters) into its new temporary parking space. To help better understand the dynamics of a retrorocket landing on the Red Planet, engineers used Perseverance’s Navigation and Hazard Avoidance Cameras to image the spot where Perseverance touched down, dispersing Martian dust with plumes from its engines.

I'd read before that they just send it a spot to go to and it decides how to get there. Can they also just send basic steering and direction commands like a remote control?
Not really as it takes at least ten minutes for signal from earth to reach Mars. You cannot directly control something with that type of time lag. The time gap can actually be over 20 minutes - depending on where the earth and Mars are in relation to each other.
That is why it took so long for rovers to be sent to Mars. They had to wait for autonomous capability.
The Russians were driving a remote controlled rover on the moon in 1970 but the time lag between the earth and the moon is about 1.5 seconds - so it is (just about) doable.

If they ever move Perseverance, maybe the scenery will change a bit.

I thought it was a 30-day test campaign, starting 60-90 days after launchI do wonder how long it'll be. They need to roll away from ingenuity, and ingenuity is supposed to fly within 30 days of launch, so it can't be long on that schedule.
