A ski area trail map holder is provided for use with a ski pole. In one form, the holder comprises a tubular housing having a spring biased roller therein. The housing is attachable to the ski pole at any point along the pole. The ski area trail map is releasably secured to a map cover which is extendable from a retracted position in which it is rolled on the roller, to an extended position in which it is outside of the housing. The map cover comprises two transparent sheets, each of which is attached at one end to the roller and each of which has a free end located outside of the housing. A locking mechanism is provided for securing the map cover and/or map in an extended position. In a second embodiment, the ski pole itself acts as the outer housing for the map holder.
