Abstract

The red snow phenomenon called ‘Akashibo’ is usually observed from May to June during the melting snow season in Ozegahara, Japan. The red snow takes its color from the reddish-brown particle about 10 μm in diameter that were found to be the round resting spores of snow alga, Phacotaceae Hemitoma sp. They were covered by spiky lorice with Fe compounds as their major components. These results suggest that the red snow phenomenon is mainly caused by the spores of Hemitoma sp. The vertical distribution of spores in snow suggests that water movement from the marshland surface towards the snow surface causes on accumulation of spores in the snow, and thereby giving rise to the red snow phenomenon.
