Abstract

Two parallel seismic reflection lines were oriented transverse to ice flow. These data show that the till layer varies in thickness but is continuous over almost the entire length of the profiles with an average thickness of 6.5 m. The upper surface of the till layer is smooth, but the lower boundary is fluted parallel to flow. These till-filled flutes are as much as 13 m deep and 1000 m across. -from Authors
