I hope not

Yes, unfortunately, generators are allowed and very much in use

When we stayed there we could never find a Camphost to ask the question of. Because we just stayed one night it wasn’t that big of a deal. I never heard anyone running one. Sorry, that’s the best I can do.

Yes, they allow generators, but not during typical quiet hours. No, offense intended at all, but I hope you are not using a builder's type generator, like we saw in one campsite. The man using it seemed surprised when 5 other campers approached him, to let him know that his generator was NOT the type you inflict on other campers who want peace and quiet. Enjoy your time at Black Canyon: it's a really nice campground, and just the right distance from Santa Fe.
