Blæsedalen (Greenlandic: Itinneq Kangilleq) is a large glacial valley on Disko Island, Western Greenland. The north-south U-formed valley features include icing ridges and a braided river system; Røde Elv (red river) has red sediment, which colours its water. The valley is situated north of Qeqertarsuaq and stretches northward approximately to Kangerluk.[1] The valley is fed by outlet-glaciers from Lyngemarkens Iskappe.[2] Between Blæsedalen and Grønlænderhuse, there is evidence of Paleoinuit and Thule Culture habitation.[3]
