Occasional arches and small rock formation features in Mesa biomes

As a Utahn and someone who is interested in geology, I love that mesa biomes are in this game, but also kind of disappointed that they lack many of the interesting features. I think it would be a small but cool change to add some of these features in a (gravely overdue) mesa update. They could appear as occasional features, akin to trees, of various rock formations. I think this would add some cool variation to the biome which is, in my mind at least, fairly boring to look at as it is. More rarely, larger arch formations or maybe clusters of these features (like Goblin Valley IRL) could also generate. It would also make for some interesting terrain to fight hostile mobs at night. As an addendum, perhaps fossils could also generate in these biomes, as a reference to the area's prominence in paleontology. I think these would all be small but cool ways to add just a bit more flavor to the mesa, while harkoning back to their inspiration.
