Planet Four Talk
Condolences, Jellymonster, I think when your cat was still warm he caused a weakness in the ice - hence the release of dirt.
Multiple brown fans superimposed (under?) blue fans? I'm guessing the (blue/green) frost fell from the larger, later burst of clear CO2.
Tiny #boulders to right of the dividing line?
Different textures / boundary dust layer?
Any idea why its so black and so much of it? Looks like its come from an open cast coal mine under the ice!
Old #bluefans with more recent dark fans on top?
#bluefans (coppery colour) (blown toward bottom right) originating from weaknesses in CO2 ice around boulders?
Left of the right-hand edge, is a vertical channel (not like a typical spider/lace type) parallel to this is a line of boulders: Unusual?
Yes, tiny #fans #hexagonal #cracks probably how the red "martian brain" types started e.g. http://talk.planetfour.org/#/subjects/APF0000hdp
Challenging to map out! Possible fans in there? Blotch tool wouldn't work for me this time just when its 75% blotch!
The rocky base might have caused more disruption to the typical residue footprint of a fan with changes in wind blowing over rock & ice?
I agree looks rocky. Not sure about fans, but just get impression that the dark areas do lean from right to left: former fans, now blurred?
#babyspider top left? Together with the hollow near center, are they weaknesses in the ice, above boulders, and future big spider channels?
Is this image zoomed in? i.e. represents smaller area than most of the other images?
#cracks Is it a mini spider bottom right, or some other hollow feature?
Any idea why lower right appears lit up, but not the rest?
#Spiders (Can't help thinking it looks like where ivy had been climbing up a painted wall - perhaps on a scientist's house?)
Would we expect "melting" or "washing/flowing" to be visible at the time these pictures were taken? (Assuming spring?)
Your telling me! Kind of looks like the #fans have sunk into underlying #spider channels as ices begins to melt, partly washing fans away.
square grid #spider network
Not sure whether this has boulders - the whole thing looks like p40 course grade sandpaper. Any ideas on cause of this texture?
#boulders look as though they have previously caused small geysers leaving behind very small #blotches and #fans
#boulders causing #fans (with co2 frost forming from some former geysers?)
boulders with blotch deposits from associated former geysers
#Boulders many at source of #fans
#Boulders, some at source of fans
Many #boudlers clearly at source of fans
#spiders new and older. Is this spring or summer?
#fans - some dual/multiple fans showing change in wind direction
Are we seeing here #boulders and other solid landform features apart from the surface ice/ #fan features? Also touch of #frost.
#spiders
#fans #bluefrost
And stunningly beautiful anyway. Good comments by first two - worthy of headlines. I'd like to find more if I can find the time!
Some #frost I think? Possibly earlier/edge fan material has sunk in and modified surface ice/frost so it reflects this coppery colour?
#spider #giantspider - Same question as Wassock asked - is this image at same scale as others?
Large "tarantula" #spiders
#boulders in bottom right as pointed out by michaelaye
Some of the rocks or boulders have small shadows facing top left, with or without the occurrence of fans. Light from bottom rt, no craters.
#fans produced downwind of #rocks (which have caused weaknesses in ice and CO2 escape?)
Warm? Its freezing out here! Great image anyway.
#spiders #fans #blotches surface features beginning to wear away/sink in as ice underneath is gradually melting deeper along spider troughs

#fans #spider #frost Stunning picture - the thread-like troughs with dark deposits & lighter frost, like fungal hyphae - deceptively organic

I think the clangers' holes had lids? I'm still thinking a rock under the ice might play a part in the formation of this hole - see science
Not sure whether these are blotches, or fans obscured by subsequent event such as frost?
i.e the bright bits are inside valleys, reflecting light that is actually received from bottom right. Hope this helps.
The light appears to be from upper left when brain assumes that you are seeing ridges. Right-click and "view image" - it looks like valleys.
There are no crevasses. That's an optical illusion caused by dark-coloured debris deposited on a flat surface. Just finer cracks/fissures.
Yesterday I saw white dots as convex 3d objects, some of them straddling the dark areas. Now convinced they are hollows - see science post
Might not be a crater, but certainly a hollow rather than a bump. Viewed up-side-down, the valleys are less convincing as "ridges".
I've rotated this image 180 degrees several times. Now convinced light IS from bottom right, shining into "crater" & north-south valleys.
