There's so much old stuff around here that he is basically being called out to perform an assessment every time anyone wishes to build anything.
Where we live now, for instance, there are a handful of burial mounds from God knows when (all plundered long ago), lots of old charcoal pits, a couple of late stone age fish traps in the lake in a corner of our farm.
To exaggerate just a little - where we could build our home was basically dictated by where we could find a spot noone had claimed thousands of years ago...
(Nothing quite like watching an archeologist go 'Oooh, that's interesting!' during a dig to establish whether you can go ahead building on your chosen spot...)
Something like that is happening right now here in Brno:

A massive construction project & equally massive archaeology operation - mapping the remains of old textile factories, an old channel and rail line, fish storage tanks, a mill, a villa and even a cemetery or two.
The archaeology work is wrapping up in a month or two & then the construction crews will take over the site (they already work in the areas that have been fully searched) to finish the construction project (which includes a 13 meter deep water tight "tub" due to a very shallow water table for the basement levels or 200 meter deep geothermal energy piles, etc.).
Where I live now - same island, but farther from the natural port and, hence, less attractive land in the old days - we still have a few which noone bothered to remove (to till the land underneath or to use the stones for building walls or foundations).
My kids used to love going playing around those mounds, made for excellent inspiration for pretending games, that!
e.g. Work for what is now the Queensferry Crossing bridge uncovered a 10,000 year old home:

They aren't "all over the place" in the US, and I certainly don't have a local archaeologist that I can just call up.
FWIW: The Northeastern US is quite recent with human presence. It wasn't settled until after the last ice age. Pretty much anything old is celebrated because there is so little of anything old.
Fun fact, New England has at least 71 different stonework “prayer sites” that are all astrologically aligned.
Two of the most notable are King Philip’s Cave (Sharon, MA) with a stone aperture through which a "dagger of light" appears specifically during the winter solstice, and Pole Hill (Gloucester, MA) which has fixed boulders that align with the summer solstice sunrise/sunset and the winter solstice sunrise.
Here is a research paper talking about all of them: https://neara.org/pdf/wantofanail.pdf
There are lots of historical preservationists in New England that you can call up. If you want my help finding one let me know where you are located.
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...)
Your "local archeologist" is one of the staff at the state historic preservation society [0], though you'll likely have more luck contacting a local university archeologist if you find anything.

Don't take the above as a sign that the natives were uninteresting or stupid. Just that they didn't leave much for us to learn from, both because they couldn't and because what they did was destroyed.
The UK wasn’t permanently settled until the mesolithic either. There are older artifacts like axes, but no monuments.
When we moved to the island we currently live on, our address was in a road called 'Solsteinen' (The Sun Stone), but I didn't think anything of it until I realized that the roughly hewn stone serving as the property limit marker was juuu-uuust touched by the sun on Winter Solstice. Aha.
A quick call to the local archaeologist confirmed my suspicion - 'Oh, so you're the new resident there, I'd planned on being in touch - that stone monument has been there for more than 2000 years, is A-listed and please, whatever you do, don't do anything with it. Seriously.'
