Artificial snow

In 1946, artificial snow from a natural cloud was produced over Mount Greylock, Mass., for the first time in the U.S. An airplane spread small pellets of dry-ice (frozen carbon dioxide) for three miles at a height of 14,000 ft. Although the snow fell an estimated 3,000 feet, it evaporated as it fell through dry air, and never reached the ground. The experiment was carried out by Vincent J. Schaefer of the General Electric Company. Earlier the same year, he had produced snow in a cold chamber, on 12 Jul 1946.
