[Bruce Jungwirth]

You might also want to epoxy the rebar cage into the bedrock for increased stability.

You could dig down 2 ft to the bedrock, and build concrete forms to extend the rest of the 4 ft anchor above grade, letting the partially buried block rest on the solid rock.  You would have a 2 ft high 4' X 6' block of concrete above grade, but at least you wouldn't have to worry about keeping weeds cleared away from the anchor points, or someone running over a guy anchor with a mower. The soil on top of a buried anchor contributes infinitesimally to its staying power.
