Investigating Sedimentary Rocks To Understand Past Wet Climate Of Mars, Emily Harper

Senior Honors Theses

The “deltaic” geomorphology in the Eberswalde Crater is often considered a “smoking gun” for the warm-and-wet ancient climate of Mars. The Crater displays sedimentary features, which many argue, can only be found in a river-delta system (Bhattacharya et al., 2005). However, with the advent of high-resolution images, the Eberswalde Crater delta’s geomorphology has been revealed to be more complicated than could be seen previously. These high-resolution data suggest that the development of the Eberswalde delta is likely more episodic (Schieber 2007). While better resolution data has placed doubt on the wet Mars hypothesis at the Eberswalde Crater, the opposite is …
