The Chief boulder is designed to be safe and accessible for both children and adults. RockCraft’s largest piece overhangs on three sides and has a gentle ramp with large friendly holds for easy descents on the fourth side. The Chief is designed for traversing both vertically and horizontally with many holds that allow for countless route possibilities.
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 and shipping. 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 abrasive 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 freeze/thaw cracking.
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.
