In Nova Scotia all archaeological sites (both known and unknown) are protected from disturbance by the Special Places Protection Act.....
I bet the correct reading is: All archaeological sites
ON FEDERAL LAND. Not all archaeological sites, border to border. Ie.: on private, city, county, state, and federal. Is that to say that every NS purist archie would see it that way? Or course not. Consider the following:
The SAME "subrogation" trickle-down logic has been advanced by USA archie minded persons and cities and states too. It works like this: An archie (bless their little hearts) feels that ARPA applies to all public land. Hence NOT just "federal" land, but likewise state land, county land, and city land (since those are all simply sub-categories of public land within the larger boundaries of federal, right ? Ie.: states are a sub-part of fed. And counties are a sub part of state, and so forth.
Thus you have silly logic that was perpetuated by some archies in one state, saying that their state was "bound" by ARPA (as if that were automatic), and extended downwards to county and city. So the ivory tower university archie was abhored by the notion of md'ing at city school yards, for instance. And cited that archaeological sites were protected. But was making a leap of logic to assume that ALL public land is an "archaeological site". Versus sites DEEMED AS SUCH (like by the trinomial system of designation). Their logic was easily torn to shreds. But it didn't matter. It caused md'rs in that state to "shiver in their boots".
Or how about the archies in Oregon who had a "hissy fit" over some bottle digger who was profiled showing his bottle collection in a "local interest" news story. An archie who picked up his morning newspaper (or turned on his TV to the morning news local interest blurb) saw that and had a hissy fit. Insinuating (and even citing "dire sounding verbiage") that this was "illegal" and so forth. Never mind that bottle diggers and md'rs are a dime a dozen in Oregon (both on private and public land).
So I put very little stock into what some archies say. Even when accompanied by "dire sounding verbiage". And if I were to go to NS, I would not hesitate for a minute to detect. But like here, or any country, sure, you use common sense not to tromp on historic sensitive monuments.
