Supposedly there's an associated "black mat" visible in the soil at ~12ky depth. Since I live in the middle of North America and I own an excavator, I'm tempted to see if I can find it..

Yes, it's an actual thing and you can see lots of photographic evidence [0] [1] if you look it up on google or read some of the many papers written on the subject. They're visible on many places on Earth, some even without any excavation needed. It sits pretty much as a clear separation between the previous geological epoch (Pleistocene aka Ice Age) and our current epoch (Holocene).
