HiPOD 25 Jan 2023: A Bear on Mars?

This feature looks a bit like a bear’s face. What is it really?

There’s a hill with a V-shaped collapse structure (the nose), two craters (the eyes), and a circular fracture pattern (the head). The circular fracture pattern might be due to the settling of a deposit over a buried impact crater. Maybe the nose is a volcanic or mud vent and the deposit could be lava or mud flows?

Maybe just grin and bear it.

HiPOD 1 Feb 2023: Crater Floor Features Northeast of Reull Vallis

The objective of this observation is to determine the nature of features on the floor of a small crater. Part of the floor is covered with rough-ridged material. One side has smooth walls; the other side seems to have material moving toward the middle since it has grooves that are barely visible in a Context Camera image.
