This probably isn't what you're thinking of, but here's something cool.

Even though Pride Rock has a very organic and natural look, it's pretty far from that. It isn't just some random pattern of rocks, like what you'd see in clouds. It's symbolic, in a way. Like a few other things in nature, Pride Rock exhibits some mathematical patterns--the same patterns that objectively determine beauty.

You may have heard of the golden ratio before. If not, I'll explain. Have you ever looked at a shape and thought, "that's too long, it doesn't look right," or "that's too short, it doesn't look right?" Okay, yes, it's a little weird. But it's actually a thing. Imagine a rectangle with sides A and B. The most aesthetically pleasing rectangle has sides with a ratio where (A + B)/A = A/B. Through a bit of algebraic manipulation, this means A is 1.61803398875... times longer than B. This number is called Phi, the golden ratio. Shapes that exhibit these dimensions exist all throughout nature, like in sea shells:

And the human body:

And if you notice, this is roughly the same shape as some man-made things, like buildings, sports cars, laptop computers, and widescreen televisions. Once you recognize that shape, you start to see it everywhere.

Guess what, though? It's also roughly the same shape as what you see in Pride Rock. The image below is 485 pixels by 300 pixels, which is a pretty close approximation to the same golden ratio.

Also, notice the four lines I drew over the image. The lines divide the image into nine equal-sized rectangles of the same proportion. What's interesting here is that the endpoints of Pride Rock meet the outer rectangle at the lines of the thirds. This is what gives it its aesthetically pleasing shape. It just looks "right."

Now, here's where the facts diverge, and I toss my own reasoning in. I believe the reason why it has such an aesthetically pleasing shape like this is because it's supposed to represent home. It's supposed to feel beautiful, strong, magnificent, warm, regal, and welcoming. It's because of subtle design choices like this on Disney's part that make this movie what it is.
