Winter storm rolls over the Grand Canyon in timelapse
Clouds and curtains of precipitation drift over the canyon's red cliffs in a timelapse.
Timelapse footage from Yaki Point at Grand Canyon follows a winter storm as it moves across the canyon.
Cloud shadows glide over layers of red and tan rock while distant shafts of precipitation sweep down into the valley.
Park officials advise winter visitors to check road and weather conditions before setting out.
