Fig. 14.5
Magellan radar mosaic of the Fortuna-Mesknet dunefield. These appear rather more extensive than the Algaonice dunes. Similar to
those, the dunes appear to be transverse, orthogonal to the prominent windstreaks. Credit NASA/JPL
Fig. 14.6
The asymmetric
slopes of microdunes lead to
enhanced brightness when
viewed from the slipface side
than when viewed from the stoss
side, an effect that is apparent
even when the dunes themselves
are too small to be resolved. See
