The NEGIS N1 3D horizon is located at the onset of Greenlands Northeast Greenland Ice Stream and has an age of 7.3 ± 0.2 ka (thousand years). NEGIS N1 covers an area of ∼ 250 x 90 km and is centred at the EastGRIP drill site. The geometry of this 3D horizon shows a variety of complex and high number of folds, which are increasing in ice-flow direction. A number of short-wavelength folds (100-500 m long and with amplitudes up to 100 m high) extend almost from the ice divide downstream along the shear zone of NEGIS.
