This figure shows a mare ridge situated south-west of the crater Aristarchus,
reconstructed based on two images acquired on
April 13, 2003 (yielding the shadow information) and on
August 12, 2004 (yielding the shading information). For this shallow feature,
the surface was reconstructed by directly applying the algorithm that takes into
account the detailed shadow structure, making use of the integrability constraint.
The surface profile reveals a step-like structure of this mare ridge, elevated by
250 m and 180 m above the terrain to its west and east, respectively.
