ABSTRACT:
The present invention relates to markers manufactured from skis. In accordance with the invention, the structure of a ski is modified to enable its use as an object which may be driven into soil or snow to designate the presence of underground objects, to delineate or identify a border or as a post for signage or fencing. The process of the invention relates to the modification of a ski by treating or removing the existing outer surfaces of a ski and providing new outer surfaces to the ski which may include graphics or notices specific to its new use. In order to inhibit the removal of a marker from soil or snow after placement, the marker may be provided with a barb system on its underground portion.
