(IAU Directions) (see Herodotus): The great serpentine cleft, discovered by Schroter, October 7, 1787, is in many respects the most interesting object of its class. It commences at the N. end of a short wide valley, traversing mountains some distance N.W. of Herodotus, as a comparatively delicate cleft. After following a somewhat irregular course towards the N.E. for about 50 miles, and becoming gradually wider and deeper, it makes a sudden turn and runs for about 10 miles in a S.E. direction. It then changes its course as abruptly to the N.E. again for 3 or 4 miles, once more turns to the S.E., and, as a much coarser chasm, maintains this direction for about 20 miles, till it reaches the S.W. edge of a great mountain plateau N. of Aristarchus, when it swerves slightly towards the S., becoming wider and wider, up to a place a few miles N. of Herodotus, where it expands into a broad valley; and then, somewhat suddenly contracting in width, and becoming less coarse, enters the ring-plain through a gap in the N. wall, as before mentioned. I always find that portion of the valley in the neighbourhood of Herodotus more or less indistinct, though it is broad and deep. This part of it, unless it is observed at a late stage of sunrise, is obscured by the shadow of the mountains on the border of the plateau. Gruithuisen suspected a cleft crossing the region embraced by the serpentine valley, forming a connection between its coarse southern extremity and the long straight section. This has been often searched for, but never found. It may exist, nevertheless, for in many instances Gruithuisen's discoveries, though for a long time discredited, have been confirmed.

- Depth data from Kurt Fisher database
- Viscardy, 1985: -1 km
- Cherrington, 1969: -0.16 km
- Feature with the third largest number of transient lunar phenomena reports: 20; (A.P.S. Crotts, 2007).
- Elger repeats the usual story of the discovery of this feature by Johann Schröter in 1787. According to former Sky and Telescope editor Joseph Ashbrook, "Schröter's" valley had actually been seen by Christiaan Huygens and recorded by him as early as May 1686, although this fact was little known until the publication of Huygen’s Collected Works in 1925. - JimMosher
- Thermal anomaly walls, implying steep slopes and exposure of fresh boulders - Moore et al, 1980
- The name Schröter's Valley was part of the original 1935 IAU Nomenclature of Blagg and Müller; where, as noted by Whitaker (p. 229), W. Pickering is credited as the originator of the name, which honors Johann Schröter.
- Number 55 in Debra Hurwitz's Atlas and Catalog of Sinuous Rilles.
- The name was latinized to Vallis Schröteri with the adoption, by the IAU, of the LPL's System of Lunar Craters in 1964.
- The "source" of Vallis Schröteri was nicknamed "the Cobra Head" by Steavenson.
- Equal Rims?
- A rille that doesn't know what to do with itself (LRO's impressive close up of the rille on the floor of Vallis Schröteri).
