Selected HiRISE imagery from both SE and NW Elysium regions. (A) ESP_022915_2070 (26.949°N, 142.844°E) shows flows down a crater slope in NW Elysium. (B) ESP_013157_2015 (21.498°N, 149.738°E) shows lava flows on the south flank of Elysium Mons within NW Elysium. (C) PSP_004046_2080 (27.49°N, 143.21°E) shows fissures and pit crater collapse feature of lava tubes in the NW region. The collapse of the lava tube has exposed stratified lava flows. (D) ESP_037802_1880 (8.1°N, 154.7°E) shows lava channels and accompanying lava levees within SE Elysium. (E) PSP_005984_1850 (5°N, 156.4°E) shows pa’hoe’hoe style flows and a lava-draped channel at its terminus within SE Elysium. (F) ESP_014278_2050 (24.71°N, 143.6°E) shows the lava flow boundary between separate geologic units HVe and lHvf in the NW region. (G) ESP_028466_1955 (15.22°N, 162.45°E) shows an image from the SE with an infilled crater in the top half of the image and rootless cones (circled) in the bottom half. (H) ESP_012524_1855 (5.58°N, 153.07°E) shows more prominent rootless cone structures as well as abundant Pa’hoe’hoe analog style flows within SE Elysium. (I) ESP_034967_1885 (8.48°N, 149.19°E) shows a large crater infilled by the lava flows from SE Elysium. North is up in all pictures. The yellow arrows represent inferred direction of flows.
