Characteristics and area [km

]
Sub-region a
Flat but rocky-like sub-region with
ponded deposits
Sub-region b
A small sub-region with a prominent cliff. Adjoins Bes with similar
characteristics.
Sub-region c
Topographically almost at rightangles to sub-region a. Highly
complex sub-region with rough,
rocky terrain, smoother coatings it
places and boulders. Talus from
collapse of material from Ash is
also evident.
Anhur
(Ah)
24.47
Consolidated material with significant intermediate scale roughness
1.87013
Sub-region a
Plateau with extreme intermediate
roughness including isolated
ridges. Includes some pits.
Sub-region b
Cliffs descending from sub-region
a to the neck. Surface texture similar to that in sub-region a.
Sub-region c
With respect to the roughly ellipsoidal shape of the body, topographically on same level as Bes
sub-region a which it adjoins but
with the face being at a large angle
to Bes sub-region a.
Aker (Ar) 14.10
Strongly consolidated material
similar to the adjacent region,
Khepry. Contains a large complex
fracture system near a steep topographic slope that descends towards
Hapi. It has four distinct faces.
0.87022
Sub-region a
Contains a large set of tectonic
fractures and a smooth bottomed
shallow depression.
Sub-region b
Topographically distinct from
sub-region a but has some similarities. It adjoins Anhur where there
is a change is slope and surface
roughness.
Sub-region c
Comprises a cliff that drops
sharply to the boundary with Babi
at its base. Significant evidence of
collapse is evident along the face.
Sub-region d
Interfaces primarily with Hapi and
is a steep fractured cliff.
