In the formation processes of block stream, we emphasized erosion of the weathering material at the base of block stream. However, observations of the erosion were not carried out. In this study, we observed air temperature, precipitation, water temperature, EC and deposits at the lower part of block stream. As a result, the deposit was not observed. Water temperature and air temperature had correlation. Rain water was flowing out in short time without eroding a weathering layer. However, there are many core stones in the block stream. We considered that erosion of the weathering layer occurred under the past climatic environment.
