The Menelaus rilles are located on an elongated part of slighly elevated
terrain. Menelaus
1 has an elongated base area of 10 x 16 km2, while the dome Menelaus
2 has an elongated base area of 13 x 16 km2. The height of the dome
Menelaus 1 was determined to 180 ± 20
m , resulting in an average slope of 1.6° ± 0.10°.
The height of the dome Menelaus 2 was determined to
110 ± 15 m ,
yielding a slope of 0.9° ± 0.10°. However, these
structures might also be considered as “mare kipukas”. According to the rheologic model two domes were
originated by effusion rates of 225 and 480 m3 s-1 over a period
of time of 1.6 and 0.6 years, respectively. The inferred rheologic properties
are comparable to those of the class C2 domes in the Cauchy region
in Mare Tranquillitatis, such as Cauchy ω and τ
and the dome Kepler 1.
