<strong class="journal-contentHeaderColor">Abstract.</strong> Upright folds in ice sheets are observed on the cm-scale in cloudy bands in drill cores and on the km-scale in radargrams. We address the question of the folding mechanism for these folds, by analysing the power spectra of fold trains to obtain the amplitude as a function of wavelength signal. Classical Biot-type buckle folds due to a rheological contrast between layers develop a characteristic wavelength, visible as a peak in the pow
