This massif is shaped as a rounded dome in the surface, occupying a diameter of 20 km and climbing gently to a height of over 1500 meters.

This formation appears foreshortened when viewed from the Earth, and it has been described by Antonin Rukl as resembling an "upturned bathtub".

To the south of the Gruithuisen domes is a portion of Oceanus Procellarum that was named Sinus Viscositatis [it] by the IAU in December 2022.

It's thought to have a higher silica content, making it thicker, slower moving and faster cooling, enabling it to pile up into these structures.

Mons Gruithuisen Gamma was expected to be the landing site for Peregrine Mission One, which launched on January 8, 2024, on the maiden flight of the Vulcan Centaur rocket, the mission failed due to a leaky valve, precluding any attempt at landing.
