The Chief is handcrafted from specially mixed, 9500 psi, fiberglass reinforced concrete (GFRC).
Pumice is added to the mix for weight reduction. The concrete is additionally reinforced by rebar and
two integral layers of steel mesh. Two steel tracks are located at the base of the boulder for moving
Hairline cracking is natural and structurally does not in any way affect the structural strength of the
piece. The boulder is designed to have a realistic but friendly finish. After sculpting and curing the
Chief is hand finished with an abraisive stone to duplicate natural glacial polishing and weathering.
The Chief’s holds include jugs, crimps, pinches, under-clings, slopers, side-pulls, ledges and flakes of
various sizes and degrees of difficulty. All holds self-draining to eliminate water collection and
The Chief is hand painted and clear coated for protection from the elements. It is available in
sandstone, granite and quartzite colors. The clear coat sealant allows graffiti to be removed easily.
However, RockCraft’s experience has been that little or no tagging actually takes place.
