Downloadable US elevation, hydrography, and topographic layers. The user guides and layer documentation make useful GIS reference sources.

The elevation, hydrography, and topographic layers here are built for GIS work, but it's the user guides and layer documentation that work as notebook sources, explaining what each dataset measures and how it was produced. That makes it useful for grounding the methodology section of a notebook about terrain or watershed analysis. The layers themselves are GIS files, not something you can hand to a notebook directly.
