HiPOD: Week of 8 September 2025

	Crater Dunes This impact crater is located in the northern lowlands of Mars. The crater’s center is covered by a dark dune field, likely composed of basaltic sand grains.
	Bright Spots on Desolate Plains These bright patches appear to be persistent water frost or ice, lasting well into the summer and in some cases all the way through it.
	Ridges in Northern Terra Sabaea One of the most distinguishing features of this part of Terra Sabaea are thin, dark-toned ridges that may have formed as cracks that were later filled with minerals brought in by groundwater.
	About a Lava-Filled Crater This area was covered by a large flood of lava, which we see as the generally flat areas surrounding the crater. As the lava flowed across, some of it flowed into this crater through a low spot along the crater rim.
	Ridges and Depressions The objective of this observation is to determine the nature of a ridge and a linear depression. The ridge is flat on top in some places. The depression bears some resemblance to a stream channel. These scene is also visible in Context Camera data.
