OpenStreetMap is a dataset that can be rendered any way you want. Where did you see that map and what were the settings?

I downloaded OpenStreetMap data from OpenAndroMaps, and was viewing it in c:geo geocaching app. I figured out the difference between contour lines and trails, the second time around.

So this was probably the fault of how the c:geo app chooses to render those lines.
