Abstract: In this research work an attempt has been made to estimate the glacier retreat/ advance for the Baspa Bamak glacier of the Baspa basin, Himachal Pradesh with the help of remotely sensed data. The position of snout is not remained stationary in space and time. To study such changes there is need to generate a time series of snout position by using satellite imageries for different time period of the region. The main criteria needed to be fulfilled while selecting the imageries under this study is that the images should be cloud free (keeping additional criteria as cloud cover below 10%) and acquisition date should be correlate with end of ablation season to get snow free and fully exposed snout. Landsat images having high spatial and radiometric resolution have been chosen to map and extract the snout of glaciers. Additionally, they have uniformity and historical availability too
