Can it snow in Hawaii? Yes! (Mauna Kea, Jan. '09)

It snows here every year, but only at the very summits of our 3 tallest volcanoes (Mauna Loa, Mauna Kea and Haleakala). The snow level almost never gets below 9000 feet in Hawaii during the winter, but since these mountains are taller than 13,000 feet, 13,000 feet, and 10,000 feet, respectively, they get dusted with snow a few times a year.
