I just took a peek, and the weights are per cubic yard, not per ton. A ton
is 2000 lbs. whether dense or not. [A pound of lead weighs the same as a
pound of feathers.]

Mike is correct that the black is more dense than the red, which is all he
was saying, I think.

Mike's note is a welcome one, and right on, otherwise. I grew up in the
area, and in the non-metallic minerals business. It's amazing how much
easier it is to find such information, now, with a little help, like Mike's.
