I guess I don't need limestone rocks then just to fill the ravine and stop erosion. What other large rock should I consider economically speaking? I have "blue" rock or "green" rock quarrys all around me in east Texas. It is some type of conglomerant rock. They use it for driveways all around here. Can normally get it in any size I want.

Dear Alcohol, We had a deal where you would make me funnier, smarter, and a better dancer... I saw the video... We need to talk.
