Preview image: Winter storm deposits snow on Mauna Loa's summit

Preview image for video: This Quicktime video shows a time-lapse sequence spanning from dawn to dusk on Tuesday, January 28, using images collected by our webcam near the summit of Mauna Loa Volcano (13,680 ft above sea level). The dawn is sunny with clear views across the summit caldera (Moku‘āweoweo), but this clear weather soon deteriorates into thick clouds and steady snowfall as a winter storm arrives. This video shows the potential for rapidly changing weather conditions in Hawai‘i's alpine zones.
