Dome	Longitude	Latitude	Diameter [km]	Heigth [m]	Slope[°]
Cavalerius 1	-70.28°	3.60°	27x25 ± 0.5	188 ± 20	0.83 ± 0.1

The dome lies near Cavalerius A and Hevelius A in a complex region known as Hevelius Formation,  showing evidence of ancient (pre-Orientale) mare volcanism and cryptomare deposits. It has a base diameter of 27x25 km. Its height amounts to 188 m and the average slope angle ξ corresponds to 0.83°. 

Cav 1 belongs to class C₁ in the scheme of lunar domes classification. Cav 1 shows a low flank slope of 0.83°, presumably as a consequence of the moderate viscosity of the lava from which it formed and the high lava effusion rate. Domes of class C have diameters between 8 and 25 km and relatively low flank slopes typically below 2°. Domes formed from spectrally red lavas of low to moderate R₄₁₅/R₇₅₀ ratio with large diameters between 13 and 25 km and large edifice volumes of several tens of km³ are assigned to subclass C₁, while domes with smaller diameters between 8 and 13 km and lower edifice volumes are assigned to subclass C₂.
