I've been staring at these old expedition maps, and there's a weird marker that looks like a secret. Think your navigation skills could help me figure out if it's just a mistake or a clue?

The marker is a small, three‑pointed star that’s been drawn in a darker ink than the rest of the map. It sits a little off the usual grid lines, about a third of the way down a ridge line that runs north‑south on the map. The star’s base points toward a narrow pass marked by a wavy line on the right side of the map. To the left, a faint water droplet symbol sits near a dotted line that might represent a stream. The legend indicates that three‑pointed stars usually denote a hidden or unofficial waypoint. But this one’s slightly skewed, as if someone added it after the main survey was done. I’d flag it as a possible clue and cross‑check the surrounding coordinates with the map’s scale to see if it lines up with any known features.
