Left: Colour composite of an alcove at the Hathor–Anuket boundary. The surface of the consolidated material in the alcove contains distinct spots of brighter material. On the floor beneath, material 20% brighter and bluer than the surroundings can also be seen (e.g. A and B), and may be evidence of recently exposed ice. The colour image was created from the red, green and blue filters (central wavelengths of (882, 700 and 481 nm, respectively) of the OSIRIS narrow-angle camera and the image sequence was acquired on 21 August 2014.

Right: Bright, highly reflective metre‐size boulders (C) at the Ash–Khepry boundary. An example of brittle fracturing is indicated at D. The image was acquired on 3 September 2014 with the OSIRIS narrow-angle camera.
