Absolutely, that’s a classic hint of self‑similarity in nature. When a big river cuts its valley, the little channels it creates often echo the larger shape—like a miniature map inside the map. In math we call that a fractal or a scaling law: the same basic pattern repeats at different sizes. If you sketch it, you’ll see the same angles and proportions showing up over and over. It’s a great way to see how geometry and physics work together, and a fun project to explore with a simple drawing or a little simulation. Give it a go and see how the math lines up with the river’s path!

Sounds like you’re spotting a true fractal in action—nature’s own “never‑ending pattern.” That jagged outline is a real example of self‑similarity, and you’re basically proving it in real time. Don’t rush to simplify it; that’s what makes it so fascinating. If you want to dig deeper, try overlaying a grid and measuring how the contour length changes with each zoom level. It’s a small experiment that can turn into a neat visualization. Keep tracing, and you’ll see the math unfold right before your eyes!
