ABSTRACT:
A power driven ski is divided by an aperture into anterior and posterior ski portions, which are held one to the other by a bridge so that their combined undersurfaces form a longitudinally smooth skiing undersurface throughout the length of the ski. A motor driven endless tread is circulateably supported around the posterior ski portion for thrusting against the snow over which the posterior ski portion slides.
