The Petermann P1 3D horizon is located at the onset of the Petermann Glacier and covers an area of approximately 156 x 95 km. Horizon P1 is ∼ 12.0 ± 0.9 ka old and represents approximately the transition from the last glacial period to the Holocene period. It is located on average 1 km below the ice surface. The horizon is mainly characterized by open cylindrical folds with the fold axis oriented parallel to ice flow. The amplitudes of the folds reach up to 1 km with a wavelength of 10-15 km and are highest in the centre of the data set.
