We report a form of incommensurate charge density wave localisation in the insulating ternary oxide YbFe2O4. This state has a unique signature in the form of tightly wound ‘helices’ of scattering in reciprocal space. Below T ≈ 320 K the helices break up into Bragg peaks with intensities modelled quantitatively by a helical incommensurate strain pattern.
