...Robert E. Jacobsen; Devon M. Burr Abstract The Aeolis Dorsa region of Mars preserves many ancient and topographically inverted fluvial deposits, some of which represent analogs to pre-vegetated meandering fluvial deposits on Earth. The regional stratigraphy of the Aeolis Dorsa preserves a tradition...
