| Apr 16 at 15:16 | comment | added | JBH | @Dmyt thanks, your third bullet was confusing me. It made it sound like there were cliffs facing the ocean and cliffs facing the continental interior, hence my conclusion you were looking for a ring of mountains around the continent. | |
| Apr 16 at 15:08 | comment | added | Dmyt | @JBH Yes. (Also, very dramatic name for a normal cliff...) | |
| Apr 16 at 15:00 | comment | added | JBH | @Dmyt So your continent is a larger version of Devils Tower, Wyoming, right? | |
| Apr 16 at 3:46 | comment | added | Dmyt | @JBH Cliffs, not mountain ranges. | |

| Apr 16 at 3:17 | comment | added | JBH | I thought I had a cool idea, but then I read your quesiton again. Do you mean you want a mountain range that rings your continent? Basically a hollow cylinder with a significant wall thickness having your continent on the inside and the rest of the world on the outside? If that's what you're looking for, it's either entirely a desert or, over geologic time scales, a salty, tepid swamp. Or filled with water, since rainfall has nowhere to go. | |

| Apr 15 at 16:16 | comment | added | JBH | I'm having trouble with that last bullet and I'd be interested to know how individually you can justify it. I've seen arroyos that were somewhat straight, but over any significant distance, everything zig-zags... unless you have an unbelievably homogeneous crust, every boulder will create zig-zags as most ravines are caused by water erosion. | |

| Apr 15 at 14:31 | comment | added | David R | Frame challenge: these cliffs need to only be on the side of the continent that faces outside forces. If a large ocean is on the other side of the continent precluding any invasion from that side, then the story holds up. For geological example, see the island of Oahu, HI which has very steep cliffs on one side. | |
| Apr 15 at 14:13 | comment | added | Dmyt | @MontyWild No, I just mentioned geological since I figured those are the only related processes that could create this. If there's a different viable explanation, I might accept it | |
| Apr 15 at 14:02 | comment | added | Monty Wild♦ | Does it have to be purely geological? | |
