Date Presented: September 29, 2011, at a NASA Press Briefing Instrument: Mercury Dual Imaging System (MDIS)
Of Interest: Features interpreted to be lava flow fronts
associated with the northern smooth plains deposits on Mercury. (Upper
left) Steep flow margin within a flooded impact crater (thick arrows);
narrow arrow points to possible flooding of a smaller crater. (Lower
left) Smooth plains (left) embaying rough plains (right), with flow
front indicated by arrows. (Right) Candidate lava flow fronts (arrows)
facing each other. The western flow unit is embaying a crater (E) and
flooding the hills (H) between flow fronts to form kipukas (K), islands
of pre-existing terrain flooded by lava.
