When they built the new High School in my old home town in western CT one of the local archaeologists (day job: science teacher) did some exploration on site and discovered all sorts of stuff - no funding for a proper dig so they capped it and put up a plaque about it (ISTR they put the tennis courts on top since that disturbed it least?) So, yeah, there's lots of archaeology in New England, it's just that a lot of it is literally buried or otherwise not called out. (And "in the US, 100 years is a long time; in the UK, 100 miles is a long distance" is also Just How It Is...)
