While watching this, I concluded that the one message I would send those in our collective past would be, "Thank you." What was normal for them seems insurmountable to me. It's not just that we're soft today; I don't have the skills needed to make my way in that world. They're just as smart, crafty, and innovative as we are, yes, but still, there's something about the world of 1814 that reminds me I'm suited only for my current time at the earliest.
I'm also reminded that I have nowhere near the skills of the people who did the work on this mapping project. Thank you, geologists and geographers of the past. Your data has provided essential continuity for the lives of those who have followed you.
