HiPOD: Week of 10 November 2025

	A Dune Field of Mars The science goal of our observation is checking to see if (1) dune alcoves are forming and (2) if autumn or winter frost is forming that can help to investigate a connection between them. This is part of larger mid-latitude dune field activity study. This field is just south of the central peak we imaged in an earlier observation.
	Ridge Crossings The simplicity of this observation contrasts with the formation we see here: two parallel, curvilinear ridges (one crossing an impact crater) that have a similar shape to other examples attributed to carbon dioxided glaciers. Owing to how in-filled the crater is, the ridge likely formed long after the original impact.
