Earth radiation measurements by meteorological satellites
Several more or less unsatisfactory theories have been proposed for the origin of lunar sinuous rills such as Schroeter's Valley. This paper presents a new explanation of the formation of these rills, namely, that they are valleys eroded by nuees ardentes. Characteristics of the rills, including form and association, are cited in support of this theory. Supporting evidence is found in the similarity of the rills to furrows eroded by nuees ardentes on the earth.
