I live on the Scarborough Bluffs, the real ones on the shore of Lake Ontario, not the British ones. Anyways, I said "the bluffs" at one point, and she said bluffs should be capitalized, because I'm referring to the Scarborough Bluffs. I think when I refer to the bluffs by their full name (Scarborough Bluffs) then I capitalize, but when I just say bluffs or the bluffs i don't need to. My logic is when I refer to Lake Ontario it is capitalized, but we don't say the Lake with a capital, it is the lake.
What do people think, should bluffs, on its own, be capitalized or not?
