important role in forming of SLAC: Iv is important to be free from mistakes in case of interpreting whether a slope is SLAC. As explaining in Section 4-2, few samples are hardly distin- guished from SLAC by photo-interpretation in some volcanoes such as Kirishima. However, it is not necessary to change the aforementioned conclusion. It is clarified that FDSA occurs frequently on SIAC as Shown in Table 1. Therefore, SLAC is considered to be a indica- tor of à slope where FDSA will occur. Inversely, however, it is not right that FDSA doesn't occur on a slope which is not SLAC. Because distribution of SLAC is sparse in Hokkaido and in west part of Honshu Island. The reason of this couldn't be made clear. It is a problem to solve this. It is hardly considered that a furrow is eroded only by running water because cross section of a furrow shows a U-let- ter shape. However, it is not expected that FDSA make SLAC be- cause FDSA frequently covers some furrows at once and because SLAC is sparsely distributed in Hokkaido and in west part of Honshu. SLAC couldn't be traced to its origins in this inves- tigation. It remains a question to clarify in the future. There are following topographic features referred to when we cosider how SLAC has been formed. a) avalanche chute defined by Shimokawa (1980) This avalanche chute is frequently steeper than SLAC and is eroded more severely than SLAC. Shimokawa insisted in his pa- per that the main agent making avalanche chute is snow ava- lanche. b) slope without furrows where FDSA is expected to occur There are some slopes without furrow where FDSA is interpreted to occur because of poor vegetation, steep inclination and so on. Inclination of these slopes is mostly less steeper than that of SLAC, Therefore, a group of eroded slopes are expected in snowy regions. Avalanche chute, SLAC, and slope without furrow can be arraged in order of Severity of erosion which they have suffered. There are SLAC where furrows become indistinct because of invasion of vegetation to them. This fact raises the following question. When was such furrow mainly formed? One of ways how to procure materials which are needed to Solve the remained question is to investigate distribution of SLAC in complete detail and to compare its distribution with distribution of many kinds of factors such as snow depth, oc- currence of FDSA, and so on. 6 Conclusion The result procured in this Survey are as follows; a) SLAC appears in heavily snowy region and doesn't appear in the Pacific Coast side except for high mountain. b) FDSA occurs on almost all SLACs. Inversely, however, FDSA doesn't always occur on a slope wich is neither SLAC nor "ava- lanche chute", c) Appearance ratio of SLAC relates to slope inclination and snow depth. d) Frequency distribution of inclination of SLAC is very simi- lar to that of inclination of slopes where FDSA occurs. And following questions remain, a) What is the forming agent of SLAC? VII-783
