Re 160, the right image shows the rover's tools on the rover's arm. See the full picture:

Nice overview of the channel (at left) in this image.

That hollow may have been the final resting place of an ice floe.

Maybe the water for the gully emanated from those gashes in the side of the Cape Tribulation hill (top).

That would explain why the land beyond the rim at Perseverance Valley is angled down from the rim.

Barsoomer;

Here's a sol 4820 L257 composite of the general location in your reply 163.

Looks like an interesting area to do some further work. Are those some veins in the far background? Could the gashes be remnants of long gone changes by water flows?

Winston, thanks for that image. Such a complex topography here.

I want to speculate that Cape Tribulation rose due to underground hydrostatic pressure that eventually caused water to erupt from those gashes.

Barsoomer;

You might be right!

Below is one of my composite sol 4823 images.

Besides the dark channel looking like an RSL, there are some very peculiar looking oddly similarly shaped pebbles at the bottom of the image. Hope the Oppy handlers would move a little closer to get some close ups of the pebbles.

Must have been a mud flow here back when the gully was active. If we're lucky, we might see possible fossils trapped in the mud...

Looks like an odd path for the rover to drive, along the edge of a ridge. The things we do for solar insolation?

I would like to see this brushed.

Some nice images in the latest monthly update.

Oppy is shivering through this winter. I think they should have stayed on the rim until winter was over.

Water must have accumulated here at some point in the past, leaving the fine-grained silt.

Beautiful image at reply 173! ... and the colours!

Winston, thanks for the kind remarks!

The bright circular feature here must be reflecting the sun. (The panels are dusty and should look light, but look dark here possibly because of an automatic exposure regulator.) The feature seems to be also casting a shadow suggesting it has depth.

Anyone know if this is a normal component of the rover?

I found it in the Oppy Self Portrait. It is a normal part of the deck.

This image makes it look like Oppy has torn up part of the ridge. Some dark shiny stuff underneath.

Middle of image: the wheel track has a softened profile with the cleats appearing to have been filled in. What could cause this?

Spongy ground,, notice the rocks have been pushed below the surface and the sub-surface has risen to encompass the rocks. The weight on the wheel would, if known, would give the elasticity of the ground surface. All of this is enabled by moisture.

New micros. Stark contrast of dark and light.

Re:178 That's what dry looks like.
