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.
	Scarp Monitoring 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.
