A debris separation system including a rock grizzly having relieved rails for inhibiting rock hang up, a vibrating grizzly having rods of alternating height for aligning limbs with the rod openings, a fines separating screen, and a rotary air separator for separating small rock and wood chips. The system is considered unique in its ability to distinguish rock and wood (log debris) by their physical characteristics. The vibrating grizzly rejects large rock while accepting long narrow limbs, and the rotary air separator separates rock and wood of the same general size and shape by reason of mass differential i.e. the more dense rock is less effected by air suction then the less dense wood.
