HiPODs: Week of 20 January 2020

	Frosted Gullies Gullies on Mars form during the winter, fluidized by carbon dioxide frost, so we monitor these sites for activity throughout the year.
	Dunes in Briault Crater Active sand dunes are common on Mars, and have a variety of surface textures.
	Sandstone in West Candor Chasma Candor Chasma in central Valles Marineris is filled with light-toned layered deposits thought to be sandstones, perhaps formed in an ancient wet and potentially habitable environment.
	A Giant Gully in Kaiser Crater Dunes HiRISE has been monitoring this dune field since 2008, and it changes every year from gully erosion in the winter and blowing sand in the summer.
