Abstract
We observed both snow dimples and water channels through cross-sectional investigation of snow layers at Murodo-daira, Mt. Tateyama, on April 15-17, 2017. These snow dimples were formed by metamorphism from lightly compacted snow to granular snow or an ice layer created by water penetration. Furthermore, examination of the stratigraphy around the water channel revealed rapid formation of many ice layers and granular snow layers in a thickly compacted snow layer. Analysis of both air temperature at Mt. Jodo and live-camera images at Murodo-daira indicate that these phenomena were formed by precipitation events on April 8 and 11 and were subsequently buried by snowfall.
