Persistent slabs lie upon a variety of snow surfaces that developed during the dry period between Christmas and early January. Slab depths range from one foot at lower elevations to four feet at the higher elevations. The weight of a single person could trigger one of these slabs in very steep terrain above 7,500 feet. Below 7,500 feet, repeated warming and cooling cycles have decreased the likelihood of triggering these slides.
