Shooting cracks incline lake

Nordic skiing around the incline lake area today we observed obvious upside down snow pack (trap door skiing). Lack of a cohesive slab in most areas well below treeline revealed few cracks or whoomphing before the afternoon hours. One test slope on north facing aspect well below tree line but exposed to wind and possibly more solar radiation did produce 2 foot shooting cracks. By late afternoon a more prominent storm slab was observed on east facing aspects close to Mt Rose Highway. Note- most skiing was done on existing Nordic ski track and no data was gathered Near or above treeline.
