Abstract: Skeg structure for a snow-traveling device, such as a snowboard, a ski, and the like including structure appropriate for anchoring to such a device, a deployable, movable skeg blade, and mounting structure which is associated with that blade that promotes adjustable, travel-limited, yieldable, spring-biased motion of the blade relative to an associated snow-traveling device, and specifically, relative to the underside, snow-contacting surface in that device.
