An artificial snow skiing surface has a number of spaced-apart rigid projections extending from a base. The surface is formed by joining like tile members that attach at side-by-side and end-to-end joints to form the mat. The joints and inherent flexibility of the tiles enable the mat to conform to irregular or non-planar substrates.
