Those are the different soil horizons, which are basically just layers of soil with different properties. If you’re interested in checking out actual soil profiles, the NRCS Web Soil Survey is a super cool website for the US.

I like exploring old buildings like churches and hotels. I feel like architecture has been optimized so much to fire codes that most modern buildings have pretty boring layouts. But older buildings are completely batshit in their designs sometimes. Like woah there’s a second little staircase down here that goes to a single room not accessible by anywhere else, or just random little hallways to nowhere. Also secret little closets everywhere, it’s way more fun.
