A portable simulated overhead crevice apparatus for rock climbing practice designed to be easily suspended from fixed points. The invention comprises a structure with an internal sub-frame ( 1 ) with a rough covering ( 4 ) to simulate the look and feel of natural rock. Along the underside length is a pronounced concave longitudinal furrow. There is a plurality of apertures along the upper-side ( 3 ) and a plurality of apertures situated about the apparatus ( 5 ) through which a flexible elongated support member ( 7 ) and a flexible elongated stabilization member ( 6 ) may be removably coupled to suspended and stabilize the apparatus at various elevations and orientations from fixed points about the apparatus, such as rafters, trees, and other structures specifically constructed for the purpose of suspending the invention. There exists at least one member ( 2 ) of the sub-frame which spans the furrow and to which a safety line may be removably coupled. The apparatus is useful as a teaching medium to allow students to practice climbing simulated overhead crevices in rocks in a safe and accessible manner, as well as vertical and other orientations, and is suitable for sporting activities in commercial establishments as well as private settings.
