HiPODs: Week of 6 April 2020
|Yardangs South of Lycus Sulci|
Yardangs are composed of sand grains that have clumped together and have become more resistant to erosion than their surrounding materials. They also serve as a useful indicator of the prevailing wind direction.
Our objective is to monitor changes in a scarp exposing massive ground ice, look for evidence of sublimation, and observe when seasonal frost is present to see how this affects the slope.
