A wooden roller coaster is a type of roller coaster classified by its wooden track, which consists of running rails made of flat steel strips mounted on laminated wood. The support structure is also typically made of wood, but may also be made of steel lattice or truss, which has no bearing on a wooden coaster's classification. The type of wood often selected in the construction of wooden coasters worldwide is southern yellow pine, which grows abundantly in the southern United States, due to its density and adherence to different forms of pressure treatment.
