The 35th item in C.A.Wood's list of Concentric Craters (1978) is the one west-northwest of Clausius and northwest of Clausius E. It is noticeable on the Hi-Res scan of Lunar Orbiter 4's photograph LOIV-148-h3. Clausius itself is depicted near the frame's lower margin.

Description

This is an example of craters that are large enough in diameter to have complex crater morphology - terraces and central peaks - but don't. The walls are fairly sharp with only a few later impact scars indicating a relatively youthful age. The floor is dark at full Moon indicating that it is occupied by mare basalt. So the crater was modified by rise of magma up fractured crust under it. But it doesn't appear that the lava has covered a peak or terraces so the present walls are probably as formed. It has been speculated by Don Wilhelms that craters like this may be impact basin secondaries, but we don' know with certainty. - tychocrater tychocrater Jun 30, 2007

Nomenclature

Rudolf Julius Emanuel Clausius (January 2, 1822 – August 24, 1888), was a German physicist and mathematician and is considered one of the central founders of the science of thermodynamics. His most important paper, on the mechanical theory of heat, published in 1850, first stated the basic ideas of the second law of thermodynamics. In 1865 he introduced the concept of entropy.
