There are some interesting erosional signs in this observation, which will make for a good comparison with other intracrater fans and fluvial sedimentary landforms.
There is also an inverted channel system, possibly ponded toward the southwest. As we’ve learned recently, it’s possible that perhaps a fluid was in part of this crater, as is hypothesized for Gale Crater where Curiosity is exploring. At high resolution, we might be able to resolve fine-scale layering/bedding and/or large, transported clasts (boulders).
Reuyl Crater is approximately 86 kilometers in diameter and was named after Dirk Reuyl, a Dutch-American physicist and astronomer (1906—1972) who made astronomical measurements of the diameter of Mars in the 1940s.
