Buried surface hoar persists in the snowpack six to eighteen inches below the old snow surface. In isolated areas where this weak snow is still preserved, skiers and riders might still be able to trigger these hard slabs. These rare areas of instability are more likely to be found on shaded terrain that has not been tracked.
