Do we have any examples of music from Europe in the Early Middle ages that are *not* Gregorian chants? And I don't mean just singing styles, but also methods of instrumentation, either in compositions of the time or modern reconstructions based on our knowledge of such topics.

An entire benchmark system by Pacific Gas and Electric. Some are just recorded using county benchmarks with PG&E surveys (which would often get you way off where they were supposed to be) or benchmarks put in by PG&E survey crews, which were just as likely to be in the wrong place according to county planning maps.

Side note, Illinois was experimenting with a cork surface. We drove on some on Interstate 55, it was a smooth ride at the time. This was in 2017.

The basic idea is that magnetic north moves around over time (magnetic north and the north pole are not the same location). So if your boundary line is defined as a north south line, and you look at a compass to figure out where to put your wall, over time the direction that wall points relative to older walls, will change.

So present day scientists can use the orientation of the walls to track changes in the location of magnetic north pole.
