Any mention of lost archaeology these days reminds me of the LiDAR surveys being down in Mexico and South America that are finding not just lost cities, but entire lost metropolitan areas (with suburbs, trade routes in between, etc.). It makes me wonder if there are analogues in places like West and Central Africa. A YouTube video I'd watched about African architecture posited that there is probably much to be discovered, as the quality of vernacular housing doesn't seem to match the pride in craftsmanship of other artifacts. Turkey is, historically, one of the most consistently populated places on the planet, going back into antiquity, so if large structures there (even purposely hidden ones) can go lost for literal millennia, how lucky would one have to be to stumble upon one in more sparsely-populated regions?
