The valleys southwest of Storuman has been exploration targets for sulfide mineralizations like the Laisvall Pb-Zn deposit since the late 1900 when several mineralized boulders where found. No previous glaciogeological survey has been made. This report focus on the directions of local paleoiceflows and glacial transportation in the area of Skikkisjön, the location of the westernmost mineralized boulder, found in 2010. The aim of this study has been to create a picture of the glaciogeological evolution of the area in order to determinate possible hostrock areas. My results suggest that the geomorphology and transportation occurred during a western icedivide located in the nearby mountainrange. The survey area is characterized by topographically controlled iceflows witch appears to be linked between the valleys. The iceflow velocity was considerably higher in the major valleys compared to the surrounding areas indicated by the distribution of longtransported material.
