Abstract
An ELA determination model (GS model) developed in the integration of glacial flow model and glacial geomorphology was applied to some reconstructed late Pleistocene glaciers in the northern Hidaka range. As a result, differences in paleo-ELA were appeared between the models with and without consideration of the glacial surface topography. Also, paleo-ELAs were highly multiple in the glaciers those ice thickness are largely changed along the flow line due to the undulation of the bed topography. These results show that bed and ice surface topographies are important parameters which influences the restoration of the paleo-ELA. Readjusting parameters in trial and error according to the result of model calculations strongly suggests the possibility of more accurate three dimensional reconstruction of the past glaciers.
