Start time: 14:00

End time: 16:30

Narrative: Our second EVA to the Kissing Camel Ridge was to explore the western side of the ride. We found the cross-bedding sample just near the road; I explained its formation to Annalea and Rajvi. Annalea drew the geomorphology of the area. Rajvi and I were taking slope measurements of the sandstone beds. Later we did rock hunting on the base to understand the area more. We found the contacts, types of weathering and rocks which can be found on Mars.

Purpose of EVA: Detailed geology and geomorphology fieldwork. To collect data on the types of rocks, structures, micro and major geomorphological features and draw a map.

Start time: 13:30

End time: 16:30

Narrative: The EVA was worth it. It was a long drive, a bit difficult on Galileo Road 1104. We parked our cars near the compass rock and walked to the Candor Chasma. We explored the Canyon from the ridges first and then we went down and collected data for our research. We hiked up the canyon and explored more from the ridges. We were able to see the contact between Salt Wash and Somerville Formation. We clicked pictures of the bedding so that we could draw the lithology. It was a 3-hour EVA and every second is going to contribute to the knowledge pool of canyons on Earth and Mars.
