The Graycliff Boulder is a small, easily portable climbing island that is constructed from the Ledgewall Module system. The Graycliff Boulder is designed to be easily assembled and disassembled for trade shows, road shows, or travelling fairs while still allowing a large amount of climbing into a small space.
A Graycliff boulder can easily be modified to have one positive sloping side and one negative overhanging side. And the difficulty of the climbs can be adjusted by the types and locations of the holds. While some climbs could be geared for small children at the same time, on the same unit, the most talented climbers could be entertained and challenged by this system's features. When assembled the top is open providing limitless attachment points for banners and advertising.
