The Menelaus rilles are located on an elongated part of slighly elevated
terrain. Menelaus
1 has an elongated base area of 10 x 16 km20
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 m s

^{2}, while the dome Menelaus 2 has an elongated base area of 13 x 16 km^{2}. The height of the dome Menelaus 1 was determined to 180 ±^{3}

^{-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 C_{2}domes in the Cauchy region in Mare Tranquillitatis, such as Cauchy ω and τ and the dome Kepler 1.
